Yah, I have to agree, the sword was a bad idea. I'd have simply grabbed my aluminum baseball bat. It is much more satisfying hearing the crunch of bones rather than the slick sound of flesh being sliced apart. Plus, I am not all too keen on going to jail for murder...cuz even if the dude WAS raping a woman, to come in and chop the dudes head off would mean some serious legal issues...but to bust in and thump the dude a couple of times with a baseball bat (not in the head...just want to break bones, not kill)... not so much so.
I imagine I could do some serious damage with ole' Aluminum at full swing to the chest, knee, etc.
That said, I would imagine if I were to bust in and see a rape in progress, I am not sure I would have the wherewithal to "aim"...likely would just "go off".
