Adam Chitwood, The Wrap ; ‘Foundation’ Creator David S. Goyer on Those Season 3 Finale Twists and Why He’s Leaving the Show
"Note: The following contains spoilers from the “Foundation” Season 3 finale...
"Then you have Dusk – or Darkness – who is behaving entirely out of spite.
I don’t think he has any clue or even interest in solving the problem or being a good steward of the galaxy. I think it’s truly a guy who, the center obviously cannot hold and he knows he can’t fix things, but he can burn everything down. And I would argue that there are people like that operating in power on Earth today that have personality disorders, and Dusk clearly has a personality disorder – it’s all personal for him. A switch has been flipped, and that’s a bad person to have in charge of a weapon like that.
So heading into Season 4 he’s all alone with what little power Empire has left.
He doesn’t have a Day or a Dawn or a Demerzel to counsel him. He just has yes men and yes women who are all terrified of him, and no one to give him any sort of counterbalancing advice.
I’m sure that’ll end well.
Even as I say that I’m like, “Huh, is there anyone else like that right now in today’s society that’s operating like that?”"
