From Man of Steel
[Holding dust in his hand talking to Superman
] Look at this. We could have built a new Krypton in this squalor, but you chose the humans over us. I exist only to protect Krypton. That is the sole purpose for which I was born. And every action I take, no matter how violent or how cruel, is for the greater good of my people. And now... I have no people. My soul, that is what you have taken from me!
