Gee, tell us how you really feel. I'm guessing you played with a guy like this somewhere.
I've admitted in the thread that I do sometimes target a player or character weakness, particularly in running Multiverser. Of course, I can't kill your characters--only verse them out to another world, and sometimes I've got people begging me to do that one way or another, so I really do need to have a few tricks up my sleeve for such situations.
I also think that the Jefferson Carter NPC strikes me a lot like the Lex Luthor of later incarnations--the corporate exec of the Lois and Clark series, for example. The idea that there is someone out there who is that smart and that devious pulling strings behind the scenes strikes me as a really good comic book style villain. But then, I've not run a supers game, and I don't really know too much of how they play. I have been in games where there was a scheming devious villain working behind the scenes pretending he was on the side of the heroes and taking advantage of his insider status, but not on that scale.
Of course, one of the things that made Lex Luthor such a formiddable adversary is that he could discover and exploit the weaknesses of his enemies. He figured out how to defeat Swamp Thing (but the town never implemented his plan), and he has come inches from defeating Superman more than once. A character like that could be a very challenging foe, particularly since he's likely to be teflon to criminal charges and have excellent lawyers defending him.
