I do not recommend resorting to violence with your brother or anyone else for that matter. You are going to meet lots of people in this world who get their self worth through bringing other people down. Try not to be like them. Try to get your strength through building people up.

You really need to work on your self esteem issues and work with a counselor on this comparison you have with your brother. You deserve to be free of these issues so you can lead a more fulfilling life. This baggage will weigh you down.
