that "if" is doing a lot of heavy lifting here. I doubt the amount of effort Danauser has made (for lack of a better term, cause he sure as fuck doesn't know what the word means) to get Sylvanas to this point implies there will be either redemption or retribution. I highly doubt its the latter in this case, but we'll see.
So far we've been dealing with Sylvanas as she stands from TFT onwards, as Undead, her former consciousness being restored like a hard drive system restore doesnt jive either. The writer's intent is either to make the character suffer to grow(as per your 'reflection point'), or the redeem former failings that otherwise would demand punishment.
Given Danauser's disposition towards Sylvanas I greatly doubt this setup isn't being used to justify some sort of redemption arc. Either case, the self reflection done from this arc isn't earned and its more hamfisted than Illidan's to say the least.
