Yeah, leaving him breathing was a big mistake, IMHO. Roomie, he gets an incidental beating. If your roomie brings home two screaming children "early in the morning", you one of two things, a part of the problem, or part of the solution.
If you were not on the line with 911, or helping Dad separate this scum from this mortal coil, your part of the problem. I'm saving my kids? You got two choices, becuase I am by god coming through. Stand down, or get taken down, and if a big screen TV is handy, thats what I"ll use. Not gonna be picky, your just another hurdle.
