YOUR QUOTE: "How can your god contradict himself if he is omniscient?"
WOW! I am amazed that as a Hell bound Atheist, you actually knew that Jesus was omniscient! “In whatever our heart condemns us; for God is greater than our heart and knows all things.” (1 John 3:20)
In any event, Jesus can do whatever the Hell He wants, understood? Jesus, as Yahweh God incarnate, tests us TRUE Christians at times to see if we're paying attention to His TRUE words within the scriptures, and that I have started topics upon, where my latest one is that we Christians can own slaves, praise!
Furthering your bible ignorance along, this passage comes to the forefront: "For you know that the testing of your faith produces steadfastness. (James 1:3) Therefore, Jesus gave us two stories of the way the "Rat Fink" Judas died. It matters not in which way Judas died, but the fact that to become "steadfast" in our faith, our Jesus was obviously "testing" us! Get it? Huh?
Upon my demise, and if I go first, I will gain solace in Heaven as I look down upon your Judgment Day as our Jesus pulls the lever to the trap doors of Hell in your behalf, praise Jesus' revenge!
