A lot of good questions to be prepared to answer when it comes to the use of deadly force. I remember a scene from the Clint Eastwood movie "The Unforgiven":
Bill Munny: Hell of a thing, killin' a man. Take away all he's got and all he's ever gonna have.
The Schofield Kid: Yeah, well, I guess he had it comin'.
Bill Munny: We all got it comin', kid.
