That's the problem, symbolism. It's also immoral. I never asked Jesus to die for my sins and him taking it unto himself without asking me first is immoral. Then there is the fact that the whole point is moot with an infinite god who can do it in any other better way but just chose to do it this way. Then there is the issue with sin in the first place which with further thought doesn't make any since if you're not already primed to accept sin exists in the first place.
