Hey, Aaron the Moor from Titus Andronicus is incredibly PE, to the point where I worth him not a full post... He kills people without mercy, convinces two guys to murder and rape, then frames the two sons of Titus and has him chop off his own hand to save them, only to present the previous ruler with an image of his own severed hand and the two heads of his young.
His only regret in the end is not being able to do 10,000 more evil deeds.
