How do we save the 'bad' people of the world

(Bad as in like. Racists, homo/trans/etc.phobic, pedo whatever people)

Nobody in their right mind wants to associate with those kinds of people, so do we just leave them to marinate in the same bad views and morals forever? Are they doomed?

'Good' ppl are not responsible for saving or educating others;;
Shit takes time and not everyone has patience, especially if the people being helped are stubborn or super stuck in their ways

I feel like this thread shows off how embarrassingly simple minded I am and I kinda can't afford to care
