I'm not sure of your point or reasoning there Hold me.
I'll answer as I took it. Did Jesus not have a moral obligation to warn Judas that when he chose him as a disciple that he would do this horrible act? I highly doubt Judas went into the situation to betray him.
It's as if I knew someone would steal from me yet in return I'd get a large settlement from my insurance company. I let the person steal from. Do I not share in that crime or have an obligation to try and warn that person not to steal?
