[MCU/616 Marvel] Assuming Kilgrave was raised right and wasn't a sociopath, how would his powers work out as a hero?

Is he street level? SHIELD agent? Avenger?

He is probably a high level street tier.  He is the ultimate hostage negotiator, a perfect crime fighter (they just surrender) and able to deal with most street level criminals.

He has the potential to go above that by breaking the will of Super Villains and using them to fight against supers that he can't take on directly, but that becomes a huge moral issue.

He would be a great leader for a questionable squad like the Thunderbolts since they would obey him unquestioningly.

All of that said, his powers really don't lend themselves to hero work.  Controlling others is an inherently invasive and painful thing to do to another human being.  We jokingly refer to telepaths mind raping people on here, but that comes from a pretty big kernel of truth.  Mind control is really tough to justify as it is completely taking someone else's free will and turning them into a puppet.
