Exactly, those are all before they went into the deep end, as you say. I think we're more on about ones that were fine with the initial betrayal against the Emperor and the Imperium, but later changed their mind after the depths some of the Legions sunk to as they started to worship Chaos rather than just rebelling against the Emperor.
Would just be interesting to see them believe the reasons for turning against the Emperor, whether truly believing it, being manipulated to or lied to by their Primarchs, but then later realising they made the wrong decision.
