Strikes me as an implausible development, unless there's a seriously convincing middle part between "violent firebrand with godlike powers" and "mature, gentle, Jesus-like adult with godlike powers" that they've come up with. And the reason I find that implausible is because the godlike powers part makes any sort of personal growth hard when you don't have any respect for human institutions in the first place.
It's likely his first run in with kryptonite will teach him a little humility.
