No, all Slayer candidates are Irregulars (Karaka included). Their main purpose is to "slay" Zahard. Also, Regulars can't kill Zahard even if they try, as they are subjuscted to the rules of the Tower. The rules are made by the Guardians. The Guardians forbid any Regular from killing Zahard, due to the contract made between them and Zahard.
