Here are some popular evil choices..
Hitler -Dead
Saddamn Hussein -Dead
George Bush -Not smart enough, could be debated if he's "evil" because he didn't have some elaborate scheming idea to corrupt a whole population, he was jut trying to finish a fight his daddy picked with a neighbor years ago
Satan -Does this idea exist?
Stalin Dead
Osama Bin Laden -Dead
Pol Pot -Dead
Mao Zedong -Dead
CIA -Plausible, but not likely
So your question is, would we be upset if bitcoin was created by someone evil who died, years, decades or centuries ago (ex-CIA)? No, it would not upset me. I'd be more fascinated by the fact that these people had come back to life!
IF someone notoriously evil did create bitcoin, it would likely improve the popular opinion of that person. It could be seen as a redemption move, they're giving back to the world in a positive way.
