I can't imagine that for an all-knowing god-child, who knows that he'll soon be going to heaven to live it up, knows that he will be worshipped for thousands of years, and feels that he is doing a great service to the entire population of the world FOREVER, this would be considered a sacrifice. It's more of a symbol than anything.
As alluded to in the cartoon, countless other people have endured much worse for much more humble causes. To think that this was 'the ultimate sacrifice' is really just cheapening the idea of both 'ultimate' and 'sacrifice'.
