You will need to talk with him about the real cause(s), and depending on that you can do the right thing, then if you cant help try to find someone who can, like parents, brothers, friends ...

try and show him/her how lucky they are, and point out all there good qualitys.

Ask them why they would punish you for there problems

murder...
dat'll save him the trouble...
or a tight slap across the face the next time he mentions it...
