Batman gets the win...

That's intelligence, not being a dick.

no one else gets to make the decision of what 'rogue' is, except batman

Well, Batman is the most intelligent of them all and is able to see when one of the team is, indeed, rogue. I don't understand why you think a fail-safe would be a bad thing - if Superman was taken over by red kryptonite, wouldn't Batman's ability to take him down be a very good thing? Batman's a great detective (the world's greatest!) and can calculate others' motives, so would be able to judge when someone truly was rogue.

Yeah, but then who'd stop Batman if HE went rogue???

Batman from another world. Ever seen Justice League? Batman is prepared to take out an alternative version of himself, and he can't prepare to be taken out by himself because there are an infinite number of Batmen ready to take him down.

Batmans, you put the "S" on the end if it's a name :)
