I think Baron hit this one on the head. Peter has adjusted well relative to Bruce, and has not made it as personal, that's for sure. Peter's use of his abilities is more rooted in Uncle Ben's mantra of "With great power..." yada yada yada, vs Bruce who "says" that his war is to keep more kids from growing up without parents (it's true on some level), but in the end it winds up being much more about vengance, bordering on the psychotic, IMO.
