That woman did not passively “stand by” and watch someone die. She actively encouraged him to commit suicide. That’s a very different situation from simply not lifting a finger to help.
And you didn’t say “might be” or “could be”. You said “ it’s a criminal act (manslaughter) from your part”. You are the one disseminating misinformation.
Am i advocating letting people die without lifting a finger to help? Nope. But i’m also not lying to try to terrify marginalized people out of their anger.
