When I wanted Titania to be an AoS villain, I had an idea that MIGHT work for Grant Ward and what he wants for Hydra.
Grant Ward thinks killing SHIELD and maybe the Avengers will be good for the world. Like Ultron without the "slam Sokovia into the ground as an Extinction Level Event" part. And yes I am borrowing from an issue of the 2000s BATGIRL series.
"The problem is apathy. People just not caring, and counting on their heroes in colorful costumes to save them and everyone else. Well, when they see their heroes dead on the ground, that will inspire them. The heroes won't save them, so they will have to save themselves. And they will. Apathy will die. The world really will finally become a better place."
