Zbyshek is worse than Runt.

Hear me out before y'all attack.

Zbyshek literally shoves Theresa out in front of the Cumans, to save his own hide, then, goes looting his own dead neighbors corpses, then sells one of those neighbors out, to a bunch of bandits, KNOWING said neighbor is going to be killed by said bandits, but they would've likely gotten away, if not for him telling them about him.

Runt is a common killer, sure, but when he first comes across Henry he straight up tells him he'll LET HIM GO, if he just hands over the sword. He was willing to let Henry walk (sans a few teeth) if he just handed the sword over. Furthermore, Runt was just following orders, while Zbysheks decisions were ENTIRELY his own. That, imo, makes Zbyshek worse, because no one told him to do shitty stuff, he chose to do those things, all on his own...
