The Crucifixion story is terrible from a secular standpoint as well, though. Talking purely from a literary standpoint here, Jesus' whole story is leading up to this big heroic sacrifice except, you know, it's not. Even ignoring the fact that as an omnipotent being Jesus is literally incapable of sacrifice, he gets better. He stops being dead! He doesn't even spend a full week before he's back up and all better. Christ's resurrection completely destroys whatever weight and gravitas his 'sacrifice' had.
There's a reason most writing guides mention that when you have a heroic sacrifice, or any character death, you shouldn't bring them back. It cheapens their death and makes meaningless. The story of Christ would work far, far, far, better if he stayed dead.
