So a common theme in superhero or fantasy stories is one where society decides people with powerful abilities are a threat and need to be regulated or "controlled" in some way. This is generally presented as a bad thing that violates their rights and freedoms.
My question is - what's a realistic solution to the fact that, yeah, no, having people walking around with the power to shoot fireballs out of their fingertips or vaporize a crowd with their laser eyes does run a risk that eventually one of them will turn into a mass-murdering supervillain, but is also a solution which doesn't involve imprisonment or forced servitude or other repressive means to stop people from potentially killing dozens of people in a blink of an eye?
