Sometimes when I pray to God I ask why He doesn't make everyone normal. I don't know if it's the story about angel and demons why we assume that beautiful people are good while those had a bad apearrance are not and we don't like them. But as I grow up I understand that it's only immaturity that makes us feel that way.
That's just how the human brains work and doesn't going to change but not everyone are like that. I beleive that people are good inside and it depends on who they are surrounded with. We shouldn't be judging by just appearance but it's hard if you experienced a bad thing.
