Mindless evil, like the guy doing all the talking in pic related. I half expect this guy to explain that he's drinking freshly-squeezed puppy blood. Where are all these sociopaths supposed to come from? And it's not just comics (though worst there), I see it around; fantasy literature is full of these people. It's like they've been given the opportunity to not have to worry about ethics, and are reveling in it. Basic common sense should have the guy in this picture reducing the subject's pain, if only for the look of the thing to the team he's working with.
