It's irrelevant if it's taken literally or figuratively.
Point of that is, human ego, which is birthed from the MIND is what causes pain, suffering, and many evils in the world.
Even if the watcher angels didn't corrupt us, our ego will do it for us.
Think of all the "isms" that mankind invented throughout history that had good intentions but only ended up causing more pain and suffering.
And everyone I know whose minds are too noisy and can't stop thinking are miserable one way or another. Even the ones whose ideas I mostly agree with.
And with that said, if ANYONE had absolute power and you enforce your utopia vision upon the world or on an area of the world... it is bound to cause pain and misery no matter what it is.
