At any rate, the salient point here is that this guy clearly still doesn't get it. The problem is not that he killed a lion that had a name, or was "popular" with locals; the problem is that he, Walter Palmer DDS, enjoys killing things just for the sheer fun and pleasure of killing them, and he gives zero fucks whether the animal in question is already endangered to the point that every act is an impactful destructive act.
Hang your fucking trophy on that, asshole. You're part of the problem; you are what's wrong with humanity. And either your actions mean nothing in the scheme of things, in which case nothing you do means anything at all, or karma is actually a thing, in which case you are well and truly -- and deservedly -- fucked.
