Anyone see the Family Guy where Brian hits a dog while driving drunk and kills it? He tries to turn himself in for murder and everyone laughs?
Animals kill each other all the time, and in much more violent and painful ways than a quick shot to the head. He is eating it, it's all good. Squirrel is pretty tasty IMO. The ways animals are treated on most farms are far more cruel.
