Do you realize in the real world how hard it is to go out and save someone as they need saving from muggings and... ?
Superman and Daredevil have super hearing, everyone else cruising around for trouble has the same odds as winning powerball as they do finding trouble.
Unless we are talking about Central Park after dark.
Okay, think about this.
Why stalk hapless potential victims into the darkened woods waiting for them to be victimized, when you can tell these idiots not to go in there where the drug dealers and murders are frolicking with abandon, which you don't need super powers to do, or you just wander around the Park shaking trees trying to flush all the thieves and sex maniacs out before the steal or flash what's under their trench coat at any passer by at 11pm, which is precrime and makes you a super villain rather than a super hero.
