Quote by Black Widow (Age of Ultron)

"I've been red in the ledger. A lot of red. I'm not going to get it out."

"The hardest thing is living with yourself when you know what you've done."

"I know what it's like to have power forced upon you. It's not freedom."

"Everyone I've ever cared about has left. But I keep moving forward."

"Some battles are worth fighting."

"Sometimes you have to become the monster to stop the monsters."

"Skynet sent me back through time to kill you."

"War teaches us the value of peace."
