Exo 3:14  "God said to Moses, "I AM WHO I AM." And he said, "Say this to the people of Israel, 'I AM has sent me to you.'" 
His death was planned and sealed only by Him. He was Absolute Love and no one could take His life, but He could lay it down. The horrid death of crucifixion was chosen, it could not have happened any other way at any other time. 

Joh 18:29-32  "So Pilate went outside to them and said, "What accusation do you bring against this man?" They answered him, "If this man were not doing evil, we would not have delivered him over to you."  Pilate said to them, "Take him yourselves and judge him by your own law." The Jews said to him, "It is not lawful for us to put anyone to death."  This was to fulfill the word that Jesus had spoken to show by what kind of death he was going to die." 

Absolute Love has a purpose, to be glorified as king of the universe. To overflow in absolute love to those who hear and listen.

Joh 18: 33-38 "So Pilate entered his headquarters again and called Jesus and said to him, "Are you the King of the Jews?"  Jesus answered, "Do you say this of your own accord, or did others say it to you about me?"  Pilate answered, "Am I a Jew? Your own nation and the chief priests have delivered you over to me. What have you done?" Jesus answered, "My kingdom is not of this world. If my kingdom were of this world, my servants would have been fighting, that I might not be delivered over to the Jews. But my kingdom is not from the world." Then Pilate said to him, "So you are a king?" Jesus answered, "You say that I am a king. For this purpose I was born and for this purpose I have come into the world--to bear witness to the truth. Everyone who is of the truth listens to my voice." 

Joh 12:25  "Whoever loves his life loses it, and whoever hates his life in this world will keep it for eternal life."
