W hy crucifixion? Jews wanted him to be killed through crucifixion, so they can prove that Jesus is not a beloved of God, rather the curst of God is on him. Jews could have killed him easily as they were in hundreds of thousands in number and very strong. If killing should had been their desire, they could have done it easily. Just like they paid thirty pieces of silver to one of his disciples, if they would have paid him more, he might he have done this service too. But they wanted him to be crucified so they can prove that he is not from God, rather he is an imposter and a fabricator. If he was from God, than God will definitely save him. May be that was the reason that Jesus was so reluctant to suffer on the cross. A killing by torture
