Simple As An Axe.

Karakhur is a raving madman. One could expect no less from a Slayer. It doesn't matter if he's charging headfirst in a mob of greenskins or if he's just pushing you to step aside so he can reach the bar to get another tankard of ale, he will stop at nothing and probably won't be stoped too.
He's not argumentative at all, and can be easily reasoned with, as long as you tell him to slay more greenskins -- no matter where -- and don't stand in his way.
