If people want to save scum why does it matter? If you cant control yourself then an iron man mode would be the best solution for everyone. Save scummers can save scum and enjoy the game as they like, people who don't want to save scum can not do it, and those who don't even want the temptation can turn on iron man mode. Win win win.

Of course the game needs to get more stable before an iron man mode is introduced.
