Props to the dad. The perv deserved more than what he received.
I probably would never tell this to someone in real life, but if I were at home and an armed burglar broke in and I had access to a weapon, I would make undoubtedly sure that the perpetrator was absolutely dead before calling the police (unless I could dial 911 and get my message across without being heard first). Even if I could call 911, I'd try my best to kill the guy if at all possible.
I've literally spent hours daydreaming about what I'd do. It sounds very masochistic but the thought of someone breaking into my turf for the wanting of goods, money, or murder is absolutely terrifying and I would totally defend for it if there is an option to protect myself and/or my stuff. I won't just call 911 and hide in a closet like "Help me there's a bad guy!", especially since my community does not have a police department and I rely on the state patrols, but I won't just kill someone and not report it either.
