The same thing that has always been wrong with people. If Cain had had one at hand, he would have killed Abel in a car crash. Or if a rock hadn't been at hand, he would have strangled him--same as sitting on the head, I guess, if suffocation was the result.

There is a tiny bit of badness in everyone, except for my wife's grandmother, who was the sweetest person I ever met in my life. She lived to be 104 and then just decided she'd had enough.

Others, of course, have more than a little tiny bit. I'd say this sack of guts had more than his fair share.
