Under the law here, it's not.
The young man did not know the identity of the man he killed and we only have his word that the man "lunged" at him.
I am glad that you are completely comfortable with a man's death, especially since you didn't have to do the killing. I'm glad that you're condoning an act as you sit comfortably in front of a computer screen.
Meanwhile, a young man has to deal with the conclusions of his action. A young man, a college student, not a soldier, not a police officer, but a young man has to accept the fact that he killed a man, an action that may have been avoidable. That's not even saying if he is charged.
I've never seen internet bravado in those who've actually had to make the decision to take a life, and see the immediate results of their actions, at close quarters.
I'm glad you're comfortable.
So what legit reason did the perp have for being inside the ma'ns house?
Why would the perp go towards the man to get away?
The perp was a career criminal, sure there is a possability that he might have had a legit reason for being there but that is boubtfull next to his history.
I have known many who have taken life and some have regrets and remorse but a few have told me they have zero.
My step grandfather said he actually got a rush from killing German troops in WW2. The first man he knowingly killed, he took his helmet. He said throughout North Africa and Italy he had no problems but by the time he was in Germany and had to kill German civillians and reserve troops it did start to bother him and as the war became distant he did have regrets.
He told me that he hoped I never had to do what he did but if I was in the same situation that I should stow my emotions and pull the trigger and cry about it when I was an old man. He told me part of being a man was there is a possability that you might have to one day kill for your country or family and a man will rise to it and do just that. He saw plenty of guys in WW2 who could not do it and came home in boxes.
Another, a recent Iraq vet said " I think most guys who have problems over killing someone is that deep down, it feels good to kill someone who was out to kill you, your buddies and the people around them. You dont know how many children I saw killed and maimed by these animals wantingly. One little boy died in my arms."
So good riddence to a scumbag, we would have less crime if it was a little easier to legally kill or maim criminals who assult you, steal from you or enter your home without permission, its called personal responsability.
It was big when America was truly great, now that it's in decline, so is America.
Killing is not a good thing, but getting rid of a victimizer is and killing is but one method.
