Being the chosen one of a deity is no picnic.
We get a glimpse of Redcloak having a moment of self awareness here; panels 12 to the end. He is aware that he's been doing/seeing something wrong, though we still see that he is a servant to The Plan. The Plan has been his raison d'etre for a very long time. The fact that he can admit that he's been wrong opens a crack in the wall ... maybe there is a way forward towards the much discussed redemption. IMO, it's a hard sell, given his track record. When one is a True Believer, changing a point of view is hard with a DC in the 30's.
For example, in this case we see that he has very much an "ends justifies the means" mindset. Rather than heal the goblins/hobgoblins, he wants them raised as undead since it furthers the plan more effectively. But there is still some self awareness ... "we're the bad guys, remember?"
