This is so unimaginably wrong. Want to know why?
Consider Ancient Greek myth. They always treated their gods as something worthy of respect, but because they'd fuck you up if you didn't. But when they weren't doing god stuff, they were always dicking around with mortals and each other - a reflection of humanity's own failings.

So this whole "using adventure heroes to make observations about human behavior" is not fucking new. It's extremely old, and if you were to ask Morrison what he thought of Greek gods and heroes being fallible, he'd tell you it's fucking genius because he's a huge hypocrite and he's only saying this about capeshit because it's a hottake that many will agree with him on.

We've had eras where capeshit was escapism without any dark moral fable. And the Silver Age shows why sticking to that mindset exclusively results in eventual creative failure because there's only so much that can be done with characters that are unquestionably good or unambiguously.
