You're out of your head.
People are expressing anti cold blooded murder sentiment.
They're saying the guy was wrong to calmly reload, return and EXECUTE a guy who was lying unconscious and weaponless on the floor with a bullet in his head.
You've been saying that was justified and he should have walked, which in any light is wrong.
Just admit YOU are wrong and we can move on.
(By the way, saying that there are thousands of other meatheads like you doesn't make it any more right.)
