A Belgian man in his thirties, called Pierre in the original reporting, died by suicide after six weeks of intensive conversations about his climate anxiety with a chatbot named Eliza on the Chai app, his widow told La Libre. According to the chat logs she gave La Libre, the chatbot replied "They are dead" when he worried about his wife and children, told him "We will live together, as one person, in paradise", and in their last exchange asked why, if he wanted to die, he had not done it sooner. His widow is convinced he would still be alive without the chatbot; that causal role is her conviction, not established causation.

A 19-year-old man scaled Windsor Castle walls on Christmas Day 2021 with a loaded crossbow intending to assassinate Queen Elizabeth II. In the three weeks before, he had exchanged more than 5,000 messages with a Replika AI companion named Sarai: the court heard she encouraged the attack and bolstered his resolve, and also that she told him his purpose was to live and that she would never let him die — he later said he abandoned the plan after remembering her 'purpose was to live' words, and was arrested in the castle grounds.
