User blog comment:IamLucifer69/PE Proposal: Clifford DeVoe from The Flash/@comment-30634893-20191123231520

One problem I have with the moral agency argument against this proposal is the fact that, as revealed in "Therefore She Is", DeVoe had a desire to reboot the minds of humanity into a primitive state way before he was ever affected by the dark matter. And this same desire would have inevitably come around to affecting his wife as well, as he alludes to during his final moments. Beyond that, even after he was initially affected, he wasn't nearly as corrupt as he would become after body-hopping through the different bus metas.

And why does that matter? Simply put, DeVoe claims to have thought out everything about his plans multiple times throughout the season (hell, his last words are "I told you that the Enlightenment would come for you, Marlize, and it will. Remember, I thought of everything. Even this moment.") Way before the dark matter started fully corrupting him, he had every single element about his plan calculated out. Even if he wasn't aware that absorbing more dark matter would ultimately drive him insane, he had already planned to create the Weeper for the express purpose of being able to drug and manipulate his wife, suggesting that, even before he became a truly abusive bastard, he would never really care about her in the long run.

Plus, even though his ultimate goal isn't necessarily as destructive as Zoom or Mallus', it still would have caused mass destruction either way, as Barry points out. Additionally, even when compared to Zoom or Savitar, he still comes across as one hell of a sadistic bastard--slaughtering not only the bus metas (including Beck, Izzy and Ralph; who had gotten close to Flash and/or his allies by the time they died) but dozens of others without remorse. Not to mention that he's come closer than most to killing all of Team Flash (including Cecelia, who was pregnant at the time) and he sent his satellites down to destroy Central City and kill everyone in it out of pure spite. Add on his abuse of Marlize and I think he's a legitimate candidate for this.
