Who was the more vile?
The man who ambushed a frightened animal and sold him while leaving a child to die alone in the desert?
Or the man who handed over the child who saved his life to an imperialist regime to be imprisoned and enslaved?
All three are guilty of some of the most heinous acts in the ME trilogy (without being indoctrinated or reapers as an excuse). But which one is truly the worst of the worst? Or can you think of someone else who can beat these three?
EDIT: people bring up a point I forgot, Leng is confirmed indoctrinated on Thessia, but he at least isn't a Reaper, and the likes of Sovereign and Harbinger would almost certainly outclass any of these bastards just by sheer scale, so the point still stands.
