Break one (at least) bone in his body every day. Oh and be sure and "beat on it" several times a day. Oh and he is not to receive any food, just water (so the scumbag will stay alive longer) until he finally dies a very painful death!

Or Put him in an abandoned house. give him a DULL plastic knive, nail his Well you know to the floor and set fire to the house.

I could get more creative but this IS a family forum after all.
