1. You couldn't live with your own failure. Where did that bring you? Back to me. I thought, by eliminating half of all life, the other half would thrive, but you've shown me that's impossible. As long as there are those who remember what was, there will always be those, that are unable to accept what can be. They will resist. I'm thankful. Because now I will shred the universe down to its last atom, and then, with the stones you collected for me, create a new one, teeming with life that knows not what is lost but only what it is been given. A grateful universe. – Thanos
2. In all my years of violence and slaughter, it was never personal. And I'll tell you now, what I'm about to do to your stubborn annoying little planet, I'm going to enjoy it very very much. – Thanos
3. I am inevitable. – Thanos
4. You should have gone for the head! – Thanos
5. Peace in our time. – Ultron
