Somehow things break down for me to think to have flawed and broken super-powered characters. Wouldn't they all become super-villains instead? But maybe we have too many characters now. It took something like 10 years to have Superman and Captain Marvel, Batman not being a super-powered man, merely very well trained. Really, can you name another popular super-hero, who doesn't have super powers. Although you could make a case that money and lots of it is a super power of its own. Back in the '30s, when super heroes originated, most did not have super powers. Flash Gordon, had none, the Phantom had none, the Shadow, was semi-meta-physical, and only in the recent movie was something approaching super powers hinted.
So imagine yourself with super powers. perhaps super-strength. Can you imagine never hitting something in anger? What about flight? Say you went dancing, and hopped a little, wouldn't you hit the ceiling and cause damage that way? Say you had X-ray vision, wouldn't you get sued by lots of people claiming you were invading their privacy, whether you were or weren't. And wouldn't you be curious sometimes, and go ahead and look, knowing it was not legal or proper?
I'm not saying that humans couldn't handle super powers, but it is the rare exception not the rule, humans being flawed. Most people if given super powers would either be dead or in some more than maximum security prison. And oh so many with lawsuits up the yik-yak, it wouldn't be funny. Even if most suits were frivilous.
