The way I see it, he seems more concerned with causing chaos and I rather kill Zara or Beta. Killing krog is also fine but if he was scum why he say he rolecrush you and banish zem? I would keep silent because no one would be able to prove he did such otherwise.
He either wants to be lynched or just don't care. If you convince the others and a wagon forms you can tag me. I will gladly vote him. Well imma make like a tree and leave
