User blog comment:ImperiexSeed/Archangels are weak, don't you agree?/@comment-9249716-20151005194731

The archangels were never weak to begin with. All anyone has is purely speculation on how powerful the non-angelic supernatural creatures are. Also, if we're being completely honest, creatures like the leviathans and Eve, were never properly developed by the writers. Besides, the leviathans only killed regular angels, not archangels. Jesse destroying angels, even though one of his parents is a demon (WAAAAAY below archangels in power) was simply a goof up on the writers' part (it's said in show that a cambion's power is fueled by lucifer) and they were looking to throw in the idea of the antichrist. Overall, my point is that with the angels beings established before you got villains like Eve and the Leviathans (the only horseman who could possibly kill archangels would be death for obvious reasons, the other horsemen, highly doubtful) God and death, as well as each other, or angelic/holy weapons could kill them. The rest of what you've mentioned is purely speculation.
