Mental Illness is a hell of a thing even in younger people, and while it is good that it is becoming less taboo in the world to discuss and find solutions to it or at least prevent from causing issues, in some places it is just as taboo as it was nearly a century ago.
Physical punishment also wouldn't have helped with this and might have, in fact, exacerbated the issue. Even studies have shown that corporal punishment overall leads to worse outcomes worldwide.
Though I would say the worst and possibly most hilarious thing in this thread so far is the people going on about how it is good for the government agencies in Saudi Arabia and other countries to brutalize their citizens over petty theft and other minor crimes, but then turn around and say "we need guns to protect ourselves from our government".
