First of all, Knights were not created by the Mark of Cain. Speculation. They were chosen by Lucifer and trained by Cain. Abaddon was afraid of a recently fallen angel which was very weak. Castiel with Adina's grace easily overpowered and hold Dean. By the way the Darkness and God is equal in terms of power. Completely equal, no superior and this was confirmed by Amara herself. Seraph Castiel was way powerful than Naomi. Naomi brainwashed him thats why she could control him. In season 6, no angel besides Raphael could stand against Castiel. Season 8 was the same, only he was brainwashed by Naomi. Even in season 11, Cas was able to easily overpower 2 lower angels even though they tortured, trapped him. Also Rowena's spell was affecting him either. He is still a very powerful.
