"If a man dedicates his life to good deeds and the welfare of others, he will die unthanked and unremembered. If he exercises his genius bringing misery and death to billions, his name will echo down through the millennia for a hundred lifetimes. Infamy is always more preferable to ignominy."
Fabius Bile

Fabius Bile is a champion of Chaos from Warhammer 40,000 and a major antagonist in multiple works based in that setting - he is also a playable character model in the tabletop game and has an array of demonically-enhanced tools by which to experiment on victims.
