What? No. It's the other way around--the Orokin towers are the halls of heaven. The creatures trapped in this heaven--gilded and glorious images of their former, courser selves--are incapable of independent action, the ideal inhabitants of any orderly afterlife.
The Sentient race--all clean lines, symmetry, descending from the heavens on wings of light, sent on a mission by the Creators to prepare Paradise? If you don't see these things as angels, you are surely blind. Blind, I say!
The Warframes are humans doubly possessed--first by a monstrous mutagen, and then a second time by a horrifying child who made some kind of arrangement with a Trickster who drove those who couldn't accept his gifts to murder each other. Warframes are demonic puppets with echoes of humanity, cloned en-masse to serve as toys for children whose favorite game is finding new and creative ways to create corpses.
Everything the Tenno do is tainted by evil. And that's okay.
