> I mean killing is wrong, but so is being a dick.

I don't really understand the point you're making. Killing is orders of magnitude more wrong thank "being a dick" (meaning: making an offsensive or bad joke). I'm sure you agree, so I don't see what's the goal of this comparison.

And I think that using Charlie Hebdo in this context is a bad taste. Saying "see, it got people killed, so they were doing something wrong" is basically acknowledging that terrorism works. People that died in Charlie Hebdo did nothing to deserve this.
