I've had my house broken into while I was there, and I didn't have the slightest urge to kill the guy. Granted, it didn't get to the point that he kicked down my bedroom door, but after I heard him come in, I banged really loudly on my bedroom wall, yelled, "get the f*** out of here!", and the guy just ran away. I'm not gonna say people don't have the right to defend themselves, but people who break into houses almost never have violent intentions. Seriously, I'm not willing to kill some 20-23 year old kid simply because he wants to steal my TV. Just my perspective.
