Barry Allen: I eat a lot of snacks. I'm like a black hole of snacks...I'm a snackhole.
Menalippe: The arrow hasn't been shot in five thousand years. Men won't know what it means.
Queen Hippolyta: Men won't. She will.
Diana Prince: You wanted me to be a leader. But leaders get people killed. So I follow, always.
Bruce Wayne: I wouldn't count of the tribes of men. We tend to act like the doomsday clock has a snooze button.
Superman: I'm glad I'm alive to see this!
Wonder Woman: Me too.
Batman: Oh, now you're glad.
Bruce Wayne: Superman was a beacon to the world. He didn't just save people, he made them see the best parts of themselves.
Diana Prince: You should move on from mourning for your parents.
Bruce Wayne: You're one to talk, you ran away for a hundred years because your boyfriend died.
Steppenwolf: No protectors here. No Lanterns. No Kryptonian. This world will fall, like all the others.
Bruce Wayne: The world needs Superman... the team needs Clark. He's more human than I am. He lived in this world, fell in love, had a job. In spite of all that power.
Barry Allen: Look man, I don't know who you are, but whoever you're looking for...
[Bruce throws a batarang at Barry, who steps back with super-human speed.]
Bruce Wayne: So you're fast.
Barry Allen: That feels like an oversimplification.
Clark Kent: How did you get the house from the bank?
Bruce Wayne: I bought the bank. All of it.
Bruce Wayne: I'm putting together a team of people with special abilities. See, I believe enemies are coming...
Barry Allen: Stop right there. I'm in.
Bruce Wayne: You are? Just like that?
Barry Allen: Yeah, I... I need... friends.
Bruce Wayne: Agreed.
Barry Allen: [Holds up batarang.] Can I keep this?
Barry Allen: What are your superpowers again?
Bruce Wayne: I'm rich.
Answer: Bruce Wayne is not only rich and powerful, he's also dangerously vindictive. If you cross him or his friends, he'll pull the rug out from under you, at best, and destroy you, at worst. At the end of "Batman vs Superman," Bruce Wayne realises how horribly wrong he was about Superman; he even feels a kinship because both of their mothers were named Martha, and he was finally able to "save Martha" (something that had haunted Bruce Wayne for his entire life). I'm thinking, once Bruce Wayne discovered that Martha Kent's house was foreclosed, he acted to not merely save the farm but to punish the bank that foreclosed it. So he bought the bank and probably ruined a few financial careers in the process, out of sheer vengeance.
