It was Reed's fault really, if he'd just seen the error in his ways and the logic in what Steve was doing...Reed only has himself to blame that Ben and Sue are dead.

Hulk is probably spaced a la the Illuminati.

Namor is on Steve's side (as far as Namor is ever on any one side).

I was trying to think of the big power houses Steve would need on his side or taken down but my brain is starting to die on me.

Blackbolt's people are staying out of things. Xavier is MIA (as he often his when people need him).

Steve is very much a villain with good PR. After all he's Captain America, and well isn't this better than having to register (sure there are a lot of freedoms lost but its only to keep people safe...).

Oh slippery slopes.

I need to think of something that set him off. Maybe the death of most of the Younger Avengers or something...
