I can't agree Hill is 100% correct, but in the least I see where she's coming from.
The way the system works now, these people will likely murder innocent people 6 months from now, get stopped, and murder innocent people again six months after that. And that sucks, and people like Hill and the general public have every right to be frustrated with the system as is.
I'm not sure we're supposed to feel sorry for the bad guys, or root for Hill for that matter. But in the least we should likewise understand why the Avengers will shut this down. But yeah, I do feel a bit bad for Hill here (though I'm sure I'm in the minority). She's likely going to take a big fall here and she SHOULD... but she's just doing the best she can in an impossible situation.
