You really dont understand do you? Jesus is God, and as God he has the right to do what he wants to do with his creation. (Romans 9:19-21) You will ask me, In that case, how can God ever blame anyone, since no one can oppose his will? But what right have you, a human being, to cross-examine God? The pot has no right to say to the potter: Why did you make me this shape? Surely a potter can do what he likes with the clay? It is surely for him to decide whether he will use a particular lump of clay to make a special pot or an ordinary one?
We are Gods slaves, and are to do as he tells us. He took away our right to kill.
