Quote by Hans Gruber

"I am an exceptional thief, Mrs. McClane. And exceptional thieves steal diamonds, not gold."

"The question is not whether I can succeed, but whether you have the will to stop me."

"Mistakes are the price of doing business. I've made none."

"A man's worth is measured not by his failures, but by his refusal to accept them."

"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."
