I agree with the idea of an atonement arc being the best choice here. "Redemption = death" isn't a formula I believe in. That doesn't mean that redemption can't lead to death (in a situation where becoming good puts you at risk of being killed), or that such a result can't be part of a good story, but I also think it's good to have stories about how people actually manage to live after their change to good. There are a lot of people who've done bad things and then stopped doing bad things WITHOUT dying, and that kind of story can be interesting to, even if the drama isn't as easily compressed into 20 minutes as a redemption-so-death story arc.
