I don't know. TOS Kirk and movie Kirk did things that should have got him drummed out of the service multiple times but because he saves the Earth over and over again he gets a slap on the wrist at worst.
Star Trek III is a prime example of this. Even though Kirk was doing what we all knew was best he basically spat in the face of the Federation over the course of two movies. At the end of the day he saved Earth so they just bust him down a rank back to Captain (which is where he wanted to be in the first place).
Secondly Kirk is a super hero if Batman is. Batman doesn't have super powers, he's just a guy....who saves the day ALL THE TIME. Kirk might not have powers or something but at the rate he saves the planet I'm pretty sure he counts.
