Anyone who knew Roland Blackhand well enough would come to such a conclusion. Even I became certain that he was a bastard as I regained more of his memories in my dreams.
"…If he wasn't a bastard, he was definitely a scumbag."
Stealing, scamming, robbery, assassination, extortion, kidnapping, rape… Fine, the last one's just a joke—rape wouldn't bring him any personal benefits. Physical pleasure was meaningless to someone hellbent on revenge. But the other evil actions could give him personal benefits as well as Fate Points which he could strengthen himself with, so of course he wouldn't hesitate to do anything.
