Yes, my William Wallace scream and berserker attack with a stick will certainly be done with gusto! In fact, I've warned my wife to expect me to go off the scale.
It seems that the principle of "stop when the threat is over" is still in play here, which is probably why you say 'be sure the bones break before they hit the ground". Of course, if he's down and writhing he may be going for another weapon so I suppose I could continue, but I'm not too keen on blows to the head and suspect that blows anywhere else might just increase the writhing and prolong my difficult decision-making. If I still felt threatened, sure. But just to keep him from trying it again? I don't see how that can be justified. I think that creating the impression of "the homicidal maniac who completely beat the [stuffing] out of me before I even had time to fall down" is what I want. Comments?
Note: I recognize my junior status here - just trying to figure things out. Thanks, everyone, for your help.
