If you will notice in the verses you quoted, Jesus says that he has come to do the "will of God", because this was the reason he was sent. Even though Jesus willingly gave up his life, it was God who commanded his execution and carried it out. Just because Jesus was supposedly resurrected, does not mean he was not murdered in the first place.

John 17:2-5, "As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him. And this is life eternal, that they might know thee the ONLY TRUE GOD, and JESUS CHRIST, whom thou hast sent. I have glorified thee on the earth: I have finished the work which thou gavest me to do. And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was."
