Judas Iscariot had to betray Jesus for the whole crucified-to-save-mankind thing to work. Most people still consider him a major dick for doing it…and that’s with Jesus was being turned over to authorities who didn’t have to execute him.
It’s cruel to pretend things are kind that aren’t. People make their choices, they deserve to be held to account for them, and any story that tells you otherwise is a bad story.
