Chaos
He'd make it big that day as a villain. Right now, those simple crimes are just practice runs. His real plans will come later.
To him, it was simple. Make them think you were a low key villain. Then, BAM! You hit them with all you got. They won't expect it. It was brilliant plan.
Luthor made himself too well known. Superman had always been on his trail. The Joker, he was a joke. Batman easily foiled his plans.
But him, no… He will succeed, because they won't see it. He will bring Chaos to the world. He will be Chaos.
