a child when you took me.
Thanos : I saved you.
Gamora : No. We were happy on my home planet.
Thanos : You were going to bed hungry, scrounging for scraps. Your planet was on the brink of collapse. I'm the one who stopped that. You know what's happened since then? The children born have known nothing but full bellies and clear skies. It's a paradise.
Gamora : Because you murdered half the planet.
Thanos : A small price to pay for salvation.
Gamora : You're insane.
Thanos : Little one, it's a simple calculus. This universe is finite, its resources, finite. If life is left unchecked, life will cease to exist. It needs correcting.
Gamora : You don't know that!
Thanos : I'm the only one who knows that. At least, I'm the only one with the will to act on it.

Thanos : [to Thor] You should have gone for the head.

Loki : If you're going to Earth, you might want a guide. I do have a bit of experience in that arena.
Thanos : Well, if you consider failure experience.
Loki : I consider *experience* experience.
