This a case of when a$$holes collide. I think Karma was nuts, and he did some really stupid things to hang himself. The kid deserved a good ass whippen, but I don't think he deserved to be shot (well, maybe with a load of salt rock).
What if that was a neighbor kid chasing his pet cat into Karma's garage? I believe in the castle doctrine and the right to self defense, but I think this was a case of neither.
