Well, first off, for whatever reason, the people picked Jesus to die. Fact is, the law who had Jesus didn't think he should be put to death, but since they didn't want to upset the local crowd, they let them decide who should be put to death.
Then again, our own feeble minds can only comprehend death so far, even if we believe in a Heaven. Case in point, ask a person of faith what heaven would be like, and I'm certain you'll get so many different answers that you're head will spin. Is there a great light? Is there a St Peter at some pearly gates? Is it one big beer party? For myself, Will Rodgers summed it up pretty good when he said "if there are no dogs in Heaven, I want to go where they went".
