Stabbey is correct - you need to complete Divinity before deciding on which playable character should finish Damian in Divinity 3. I won't say any more so not to spoil your game for you but wait and see what happens.
As I mentioned before, I think that it is right to have the Divine kill Damian and I think he was brought back at the end of DKS for this reason. Now as for the Dragon knight in my ideal Divinity 3 - he / she would also be playable character. This is the only way how I can see it keeping both DK / Divine groups happy but I have no idea how this would be implemented in the game. Most probably he / she is just a computer controlled ai sidekick that appears during the game at certain points with the option of you taking control whilst the ai controls the Divine. But for the final battle it should be the Divine.
