Supergirl, Season 4

Lex Luthor:
"Against other things, it is possible to obtain security, but when it comes to death, we human beings all live in an unwalled city." Do you know who said that?

Lena:
Please, Lex, you don't have to do this.

Lex:
I'm doing this for us, for the entire human race. Listen down below. They're already cheering. And it was Epicurus, by the way. An aphorism 230 years old, and yet still as apt as ever.

Lena:
You sound like a freshman philosophy major, and you're gonna kill millions of people. The world can't live under a red sun.

Lex:
Neither can Superman. You see, sis, we as a people have become soft and fat, and stupid. [calls are made on a loudspeaker for him to surrender; he taps his watch, and an explosion is heard] Where was I?

Lena:
My god, Lex, you killed them.

Lex:
Oh, that's right. Uh, we must put faith in ourselves, but instead, we look up to him, with big, glassy eyes because we think he's invincible. But it's my duty to dispel the world of that notion. And when he dies, they will finally wake up and see him for what he really was, a false god.

Lena:
At least he's a good man.

Lex:
HE IS NOT A MAN! I was the man of tomorrow, not him! Not him!

Lena:
So it's all ego, then?

Lex:
[surrendering as armed soldiers enter] No, it's science. I want to see if the Kryptonian pretender can bleed. Even gods can die. You'll see. Everyone will see. And then, they're gonna thank me.
