I assume theres some sort of inner conflict he's having and the spoilers dont talk about it.
Its very obviously the thing (creating an army) he was trying to atone for and now he's doing the exact opposite. Theres got to be some level of regret the moment he's promoted.
Something happens at the castle, because the Knights and Imu all talk about Harald like he never betrayed them, implying they seem to not know the full story here, and if I had to guess, Loki does with Jarul.
