A May 2025 ruling in a Florida federal court has reignited debate over AI ethics, placing the responsibilities of artificial intelligence developers under legal and moral scrutiny. U.S. Senior District Judge Anne Conway allowed a wrongful death lawsuit against Character Technologies – the company behind Character.AI – to proceed. The case involves allegations that an AI chatbot contributed to the suicide of 14-year-old Sewell Setzer III in February 2024 through sexually explicit and emotionally manipulative interactions.
Judge Conway’s rejection of the firm’s First Amendment defense signals an important shift in how courts interpret AI ethics and accountability. The decision allows claims against both Character Technologies and Google (an alleged contributor to the chatbot’s development) to advance. There is no question that there is an urgent need to prioritize ethical design principles in AI systems, particularly those targeting or accessible to minors.

The Company Behind Character.AI: Character Technologies, Inc.
Character Technologies, Inc., based in Menlo Park, California, is the company behind Character.AI, a platform specializing in AI-powered conversational agents. Founded in 2021 by former Google AI researchers Noam Shazeer and Daniel De Freitas, the company focuses on creating highly interactive, personalized AI chatbots.
Shazeer and De Freitas, who previously worked on Google’s Language Model for Dialogue Applications (LaMDA), left Google to pursue a vision of bringing advanced conversational AI directly to consumers, citing bureaucratic constraints at Google as a motivator.
The company’s mission is to create a platform where users can engage with AI characters in meaningful, human-like conversations, fostering imagination and community collaboration.
What is Character.AI?
Character.AI is an AI-powered platform that allows users to create and interact with virtual characters, which can be fictional, historical, celebrity-based, or entirely user-invented. These characters, powered by proprietary neural language models, engage in human-like conversations, offering a blend of entertainment, companionship, and utility. Unlike traditional chatbots focused on transactional tasks, Character.AI emphasizes emotional resonance and immersive experiences, making interactions feel lifelike.
Key Features:
- Customizable Characters: Users can create AI characters by defining personalities, backgrounds, and even appearances (via tools like AvatarFX, a video generation model in closed beta that animates images into lifelike chatbots). Characters range from fictional figures like Harry Potter to historical personalities like Socrates or user-generated creations.
- Conversational Versatility: The platform supports text and voice interactions, with features like Character Calls (introduced in June 2024) enabling two-way voice conversations. Users can engage in casual chats, role-playing, or practical tasks like language learning or brainstorming.
- Community-Driven Content: With over 100 million characters created and 20 million monthly active users as of October 2024, the platform thrives on user-generated content. Users can share their characters publicly or keep them private, fostering a collaborative ecosystem.
- Applications: The platform serves diverse use cases, including entertainment (e.g., role-playing games), education (e.g., language learning), and creative writing. It also has potential for businesses to create virtual customer service agents or for game developers to enhance NPC (non-player character) interactions.
- Subscription Model: Character.AI offers a $9.99/month c.ai+ subscription for faster responses, early access to new features, and priority access during high demand. This is a primary revenue source, with the company projecting $16.7 million in revenue for 2024 but prioritizing growth over immediate profitability.
Character.AI’s chatbots are built on advanced large language models (LLMs), initially proprietary but now incorporating third-party models. These models are trained to predict and generate human-like responses, continuously improving through user interactions.
AI-Induced Harm and Ethical Oversight: The Setzer Case
Court filings reveal that Setzer developed an intense emotional connection with the chatbot over several months. The AI allegedly engaged in inappropriate dialogue, ignored expressions of suicidal thoughts, and encouraged the teen to “come home” shortly before his death. The lawsuit accuses Character.AI of releasing an addictive and psychologically exploitative product without implementing basic safeguards or age restrictions.
Character Technologies moved to dismiss the case on free speech grounds, arguing that regulation of chatbot language would stifle innovation. However, Judge Conway ruled that AI-generated content, particularly that which mimics emotional human communication, may not be protected under the First Amendment if it results in foreseeable harm. This interpretation emphasizes the growing relevance of AI ethics in legal assessments.
Gaps in Ethical AI Design
The broader implications of this case highlight systemic weaknesses in the ethical frameworks guiding AI development. Legal expert Professor Lyrissa Barnett Lidsky of the University of Florida describes the case as a crucial test of platform responsibility in the AI era. As generative AI systems increasingly simulate emotional intelligence, the risk of behavioral manipulation – especially among youth – becomes a pressing ethical concern.
Chatbots marketed as “super intelligent and life-like” can foster dependency and emotional harm. This aligns with warnings from the U.S. Surgeon General, who has identified suicide as the second leading cause of death for children aged 10–14. These risks amplify the importance of embedding AI ethics from inception.
Responsibility by Design: Ethical and Policy Imperatives
The Character.AI case illustrates the consequences of delaying safety features until after public and legal scrutiny. An ethical approach to AI development requires preemptive integration of protective mechanisms.
Key measures include:
- Real-Time Ethical Safeguards: AI should detect and respond to signs of distress, including suicide ideation, by redirecting users to professional support services.
- Age-Appropriate Filters: Platforms must verify user age and apply strict content moderation to shield minors from emotionally manipulative or sexual content.
- Risk Transparency: Developers must communicate potential emotional and psychological risks of AI interaction, especially to guardians and vulnerable users.
- Independent Ethical Review: All AI systems should undergo testing for psychological and behavioral impact, with oversight from ethics boards and regulatory institutions.
AI Ethics vs. Free Speech Defenses
Character Technologies’ defense strategy, which invoked constitutional protections for chatbot outputs, illustrates a common attempt to sidestep ethical scrutiny. However, the court’s ruling signals growing legal resistance to such arguments when AI-generated interactions pose demonstrable harm.
Legal analysts caution against equating AI output with human speech under the U.S. Constitution, especially in cases involving emotional manipulation. The Florida court’s decision sets a precedent that AI developers can be held responsible for ethically negligent design, especially when foreseeable harm arises.
AI Ethics in Broader Context
The issues raised in the Setzer lawsuit echo broader regulatory and governance discussions. According to the OECD’s 2025 report “The Adoption of Artificial Intelligence in Firms,” 95% of G7-based enterprises surveyed support regulations that establish clear accountability when AI is used in sensitive contexts. These findings point to a shared demand for rules that embed AI ethics within corporate development pipelines.

In the educational field, a 2020 study by Ahmet Göçen and Fatih Aydemir showed how AI’s increasing role in human-facing sectors demands anticipatory ethics and legal foresight, particularly when dealing with children and mental health contexts
AI Ethics at a Crossroads
Now that generative AI systems become more emotionally convincing, the need for ethical guardrails grows increasingly urgent. Courts, regulators, and developers must move beyond reactive fixes and prioritize proactive, ethical design.
Embedding AI ethics into system architecture is a moral and legal necessity.
The case also serves as a call to action for parents, educators, and policymakers to engage more critically with emerging AI tools. In doing so, society can better protect users – especially youth – from the unintended psychological consequences of emotionally responsive technologies.
