Well.. If I'm going to use a gun to kill someone then its
going to be for a very very good reason. Just because someone breaks into my house I would not kill them unless
they threatened me or my family.

I'm not just going to shoot them and hope some court thinks I had the right to do so. If a court convicts you on murder charges then you spend the rest of your life behind bars.

For what??!! For killing a stupid thief who was never going to harm you. NOT WORTH IT!

Think about it. If someone shoots your mother/father dead and then you find out who did it. Does that mean you can go
kill him/her for killing your mother/father. Nope. You'll goto prison.

One time my uncle woke up in the middle of the night and found some guy in his living room. The guy ended up being missing from a mental health facility and didn't even know where he was.
