Hmm yeah it`s good comparison-but they were being guided by Maxos- Maxos himself wasn`t have good and evil alighment ,Berilin was talking about his(MAxos) NEUTRALITY for Wizard Wars I think because he was man of big wisdom(it seems so during Divinity 2 events at least)
Dragon Knights his apprentices and I think they are suppossed\tought to be wisdom as far as possible
But angels they are also the deity of good...don`t know
Maybe if Larian want we`ll see angels or someone like that
