I don't think he hit the boy in the head with a whiffle ball bat. The homeowner seemed to be the agressor striking Anthony from behind with a rifle butt. For all Anthony knew, it was the end of the line for himself, so in an act of self preservation he did the logical thing and tried to stop the threat. IIRC he struck the guy in the stomach area. Had he walked in and Mozambiqued the homeowner, I might could see the "specific intent" part and would agree with Murder 1, but as it stands Murder 2 seems a better fit for now.
Just speculation mind you, but it seems plausable.
Your true colors are revealed!
