Jor-El quotes from Superman II (1980)

I ask you now to pronounce judgment on those accused: [referring to Non] On this... this mindless aberration, whose only means of expression are wanton violence and destruction. On the woman Ursa, whose perversions and unreasoning hatred of all mankind have threatened even the children of the planet Krypton. Finally, General Zod - chief architect of this intended revolution, and author of this insidious plot, to establish a "New Order" amongst us - with himself as absolute ruler! The decision of the Council will now be heard.

Guilty!

Guilty!

Guilty!

Guilty.

General Zod

The vote must be unanimous, Jor-El. It has therefore now become your decision. You alone will condemn us, if you wish, and you alone will be held responsible by me. [Jor-El signals the Phantom Zone] You will bow down before me, Jor-El! I swear it! No matter that it takes an eternity! YOU WILL BOW DOWN BEFORE ME!! BOTH YOU AND THEN, ONE DAY, YOUR HEIRS!!!

The people of your planet are well pleased with you, Kal-El. You have served them faithfully and they are grateful for it. And yet you have returned to reason with me once again. My son, I have tried to anticipate your ever question. This is one I'd... hoped you would not ask.

My attachments, um, the feelings which I have developed for a certain human being have deeply affected me, Father.

You cannot serve humanity by investing your time and emotion in one human being at the expence of the rest. The concepts are mutally exclusive.

And if I no longer wish to serve humanity...

Is this how you repay their gratitude? By abandoning the weak, the defenceless, the needy for the sake of you selfish pursuits?

Selfish!? After all I've done for them? Will there ever come a time when I've served enough? At least they get a chance for happiness. I only ask as much, no more.

Yours is a higher happiness. The fulfillment of your mission, as inspiration you must have felt. You must have felt that happiness within you. My son, surely you cannot deny that feeling.

No, I cannot... any more than I can deny the other, which is stronger in me, Father. So much stronger. Is there no way then, Father? Must I finally be denied the one thing in life which I truly desire?

If you will not be Kal-El, if you will live as one of them, love their kind as one of them, then it follows that you must become one of them. This crystal chamber has in it the harnessed rays of the red sun of Krypton. Once exposed to them all your great powers on Earth will disappear... forever. Once this is done, there's no going back. You will feel like an ordinary man and you can be harmed like an ordinary man. Think, Kal-El, I beg you.

Father... I love her.

Think, Kal-El.
[Kal-El steps into the chamber]

Listen carefully, my son, for we shall never speak again. If you hear me now then you have made use of the only means left in you: The crystal source through which our communications begun. The circle is now complete. You have made a dreadful mistake, Kal-El. You did this of your own free will in spite of all I could say to dissuade you.

Clark Kent

I, uh...

Now, you have returned to me for one last chance to redeem yourself. This too finally I have anticipated, my son.

Clark Kent

Father, no...

Look at me, Kal-El. Once before when you were small, I died while giving you a chance for life. And now, even though it will exhaust the final energy left within me- Look at me, Kal-El. The Kryptonian prophecy will be at once fulfilled. The son becomes the father, the father becomes the son. Farewell forever, Kal-El. Remember me, my son.
