AVENGERS DISASSEMBLED happened, in, what, 2005? And CRUSADE was in 2012? I don’t know that seven years can be considered “too quickly.”

And in the case of Bishop, I don’t think he was ever a villain or really in need of redemption. All through that storyline he was fighting for what he believed was the right thing, walking a hard line to protect the future–just as he’d always done. It’s just that this time he was n opposition to Cable, who was doing the same thing from the opposite position.
