That's the left's argument, blaming everything on society. You know this guy had plenty, PLENTY of occurrences where he was like "wow maybe I am actually the asshole here" or "maybe I am actually nuts, I should fix this". People are not meat robots. He made his choices and he chose the path of psychosis, bitterness and hatred. Consistently. Day after day, week after week, year after year. He chose this path. Culture can help encourage dysfunction but it was ultimately him who ate the forbidden fruit, consistently took the lowest road possible, and ended up in torment as a result. All it takes to avoid this is just TRYING to be less of a shit stain instead of constantly doubling down to protect your ego.
