He then asked if I was willing to shoot someone over my xbox.
I told him, "The xbox was besides the point. We are talking about a person intruding into my house at night with my family present. Hell yes, I'd shoot him. It's the principle of the thing. I'd shoot a hole in my xbox without blinking to do it."
Here's what I think about home intruders:
If you break into a house without a weapon and are simply trying to steal things you've consented yourself to potentially being beaten within an inch of your life. I wouldn't blame someone for killing you anyways.
If you break in with a weapon regardless of whether you're looking to rob/rape/kill/whatever then you've consented to forfeiting your life and deserve what you get.
No matter what I will never fault someone for killing a home intruder as your home is your sanctuary. Someone breaking into it would most likely lead to you never feeling truly safe inside of it again, and that's a terrible way to live day by day.
