We don't want people to hurt themselves, because we have humanity and because they become a drain on society.
I find it hard to be that black and white with phenomenons like OF, that emerge from a mix of societal and technological advancement.
There are grey zones and not everyone is fortunate enough to be taught to be responsible. Not everyone can go through life without feeling desperate and resort to doing things they would not be proud of.
We should try to educate and protect people instead of pointing internet fingers at them.
