problem is too general, lets look at general solutions:

1) Mirroring - behave and think exactly like how he is, make him understand how uncomfortable other ppl is when someone treat him that way

2) Fantasize - dun do anything practical but just fantasize him receive any sort of punishment and bad luck due to his bad behavior

3) Confront - tell him in a direct way on which behavior of him make u feel uncomfortable or sad

4) Give him hell - when he behave badly, give him double of hell time to make him learn that he is not a god that everyone shud tolerate

5) Give him love - could be the hardest method. Use love to make him understand that he dun have to behave in such negative way but being nice to ppl would gain back nice respond and treatment.

There are all sorts of impact thou. Use it wisely
