People who live in glass houses shouldn't throw stones

When someone always finds fault in someone else it means that they are feeling insecure, that they have to bring everyone else down in order to feel good about themselves. A lot of time the bullies you know are the ones who are insecure in some way. Weather it is because of grades or someone is better than them on a team most bullies have to pick on others in order to feel that level satisfaction of being better than someone else. I have been picked on and been made to feel like I was scum and that the other person was better than I was. I have, also probably, made others feel like they were scum.
