Usually people don't see beyond the surface of things and cannot understand more other than the obvious; they are used to judging a book by its cover, and that is why they don't hesitate to bully.
Unfortunately, human perception is not very developed. Everyone sees whatever they know or what they want, without considering the limitations of their knowledge or what is moral in the world. As a result, humans are a flawd species.
What people don't understand about other people -and when malevolent don't want to understand- is that a moment is not a lifetime and everyone can transform to their best self if they have the appropriate resources.
At the end of the day, what all people outright want from their life? To make their dreams come true, so as to escape from the mundane world. However, reality often prevents them from that. Others accept that fate, lacking the courage to follow their dreams or the belief that they will make it. They don't want to risk what they have built to walk on an undiscovered path that is uncertain where will lead. So, they stay in safe grounds.
The people you meet in your life, you meet them for a specific purpose: To help them and to be helped by them. So, try to spot the treasure in your everyday life, because one day you may realize you had the treasure and you lost it.
