I find Bruce more villainous looking in the scene with the two of them.
He's more intimidating, sure. But a) he's clearly over 6'6", so it's hard not to be, and b) that's not really a hero or villain trait - either one can have it. I mean, if you didn't know who they were, Superman would be far more intimidating than Joker.
Bruce, on the other hand, looks to be a conniving creep.
