Soldato
A former friend killed the little sisters. He just wanted the Adam.
If you talked with him for five minutes you would be able to guess he would be that sort of person.
I had a falling out with him over his total lack of self-awareness, empathy and remorse a few years back, funnily enough.
I think the worst I do (when given a choice), is nicking everything in sight from poor villagers homes, even when they're occupied, as Geralt.
I call it The Witcher Tax,
But murdering the Little Sisters, nooo!
