Hare Hunt, Siding with Guards, Killing Hanekin is ok?

So Henry thought it’d be fun to join the poachers and maybe in the process help Andrew somehow earn a little groschen. But when Henry met the poachers and the Hare in the woods, the Talmberg guards showed up and Henry decided he’d better stay on the straight and narrow path.

What I do not understand, is if Henry is supposed to simply follow Hare as he runs or kill him. Twice I tried killing him, and both times the guards turned on me. So maybe I hit one of them by accident or else they assume Henry’s a poacher too?

What am I supposed to do here, having decided to side with the Guards at the last moment?
