He would be in jail

jail? there's no jail that can hold the batman!

I'm pretty sure he would be called a vigilante instead of a terrorist.

If batman were real then all of his villans would be terrorist too. :/

He's already marked as a terrorist who killed Harvey

Well, they did label Batman as a terrorist.

They do label him as a vigilante. I don't think he actually does anything that's defined as terrorism.

Isn't it "was" instead of "were"

He's rich and white, he'd be labelled as "misunderstood" instead of "terrorist"

if batman WAS real, you mean

"Were" is correct. It's the subjunctive tense...imagine if something that isn't true actually became true. "If I were rich, I would..." The infinitive To Be is one of the few verbs whose subjunctive tense is different than the regular conjugation.

They labeled him a terrorist in the movie?
