People are often jerks because it "works". It gets them what they want. Your job as the jerk supervisor is let them know that being a jerk will not get them way they want. It will tarnish their reputation, diminish their credibility and eventually get them isolated, demoted or fired. Promoting a jerk is equivalent to detonating a nuclear bomb in your company. It tells everyone that the way to get promoted is being toxic, therefore everyone will become toxic. It will also make ethical people give up on your company and leave.
