I'm not sure exactly how much of his killing methods are shown, but from what I know based on what I've read about him, I vote yes. Being an established serial killer of women, children, and whole families, and having them killed in very brutal ways like having them tortured and/or mutilated, at that, is the sort of thing that stands out even in a series as dark and violent as Fate/Zero. That, along with his considerable attempted body count due to having Caster summon a demon in Fuyuki City River and his lack of resources, being a deranged, but otherwise completely normal person who relies on Caster to do the killings for him, make him stand out as an exceptionally depraved piece of work.
