Thanos

"I respect strength in all its forms."

"This moment will define your existence."

"The choice was yours to make."

"I have grown weary of your resistance."

"My resolve is unshakeable."

"Yield now and suffer less."

"The universe will thank me."

"I am inevitable."

"The universe requires correction."

"Perfectly balanced, as all things should be."

"Destiny arrives all the same. And now, it's here."

"I had to."

"You could not live with your own failure. Where did that bring you? Back to me."

"Dread it. Run from it. Destiny arrives all the same."

"The hardest choices require the strongest wills."

"I respect that."

"Resourcefulness."

"When I'm done, half of humanity will still exist. Grateful. Balanced."

"Fun isn't something one considers when balancing the universe. But this does put a smile on my face."

"The end is near."

"I know what it's like to lose."

"Your stones."

"Ah, but if you fail... then we're both dead."

"I like you. But now you're in my way."

"Gamora... did you do it?"

"Soul for a soul."

"Impossible."

"I've come to bargain."

"Your optimism is misplaced."

"I have what I wanted. The universe in the balance."
