Knight of hell below regular angel? as if... they only thing that can kill them is the first blade, they are empowered by the darkness, which is stronger than can, who empowers angels, maybe most of the knights were not so strong, but certainly above normal angel level.

Cain on the other hand, was pretty much invincible, using cas's state to judge how easy cain threw him is not valid. Cain, as directly empowered by amara, was likely immune to all angel powers, as like i said, she is stronger than god, and he is getting his power from her, that means aside from the first blade, likely nothing can kill those with the mark, Lucifer included at the time, only option is to seal him away.

Now that we know God power can be trumped, we can easily assume that Amara's power pool trumps the 'power of heaven'... Cain was the most powerful Demon ever...sure Kripke said Lilith was, but his time as head writer also said Michael was the eldest Archangel... Lilith was just his first, but Lilith was not empowered by the mark, of normal demons that encompass 99.9% of all demon's, sure, she may be most powerful, but cain breaks too many rules of demon's.

People give angels far too much credit, there not even that powerful overall compared to other things. We know that white eyed demon's can overpower angels as evidenced by Alastair, twice, and it wasn't even an effort! based on the fact that Zachariah was never confirmed a seraph on screen, and Castiel's sereph powers always seem to be lowered for whatever reason (lost grace, return from purgatory)... we can't evaluate with good evidence just how strong a seraph is compared to other angels, or demon's, as we have had very little showings and many assumption's.

We do not know how much higher seraph are in the rankings, or if Grigorii, Rit Zien, or whatever are higher... Naomi was clearly stronger than seraph cas, yet no mention of her rank is given.
