Featured Would A Christian been justified To shoot the Joker killer?

Considering that the New Testament is constantly quoting the Old Testament...yes.

The difference being, whether you rely on the law for your salvation; or you recognize that it's God identifying those things that He finds good (but knowing that even if we could somehow manage to keep every single law, all our righteousness would still be as filthy rags).

 

Of course. One cannot love his neighbor as himself and allow his neighbor to innocently fall victim to a violent malefactor. It would have been a sin NOT to shoot.

 

Aaron, I agree with you. For a believer that carries, it is a great responsibility - not to act in vengeance, but in defense of others.

There are many that don't understand - and can't reconcile following after a loving Savior with the possible need for lethal action in defense of others. I am one who knows the pain of having made that decision several years ago.

But borrowing a line from "a few good men," I would say that "my existence, while grotesque and incomprehensible to you, saves lives!"
