So... you’re infallible.

This is the trolliest response possible.

You’ve provided an excuse for this guy’s actions.

If your entire argument rests on a premise you’ve completely made up...I think you’re sort of admitting you don’t have a very good argument.

Why not? Why are you opposed to encouraging people to do the right thing?

And you weren’t there...so you have no reason to assert to all of us that this killing was justified.

How do any of the terms you use contradict the one’s the OP used?
