Totally, but most people are not emotionally well adjusted or in a place where they an introspect and build themselves up to be the better version of themselves. A lot of folks would be helped by therapy and having someone to talk through to work through this (but that's a healthcare conversation, which we don't have to devolve into here).

I unequivocally do not condone folks who go off the rails in ways that cause harm to others (self destruction and harm is similar, but a different conversation), but I've seen enough mental health challenges and crises to understand why it happens. In general, life is hard, and no one is coming to save you except yourself.
