Necron: "You stand before the final dimension, and I am the darkness of eternity... All life bears death from birth. Life fears death, but lives only to die. It starts with anxiety. Anxiety becomes fear. Fear leads to anger... anger leads to hate... hate leads to suffering... The only cure for this fear is total destruction. Kuja was a victim of his own fear. He concluded he could only save himself by destroying the origin of all things - the crystal... Now, the theory is undeniable. Kuja's action proves it. All things live to perish. At last, life has uncovered this truth. Now, it is time to end this world. I exist for one purpose... To return everything back to the zero world, where there is no life and no crystal to give life. In a world of nothing, fear does not exist. This is the world that all life desires."
Zidane: "Who the hell do you think you are!? You're not ending anything! Never, not as long as we have the will to live!"
Necron: "Foolish creature, your fears have already deluded you. One day, you will choose destruction over existence, as Kuja did. When he sought to destroy the crystal, the purpose of life ended. Now come... enter the zero world that you desire."
Zidane: "No! We'll destroy you and prove you wrong! And through our memories, future generations will see that we can overcome fear! ... We can't give up now! We have to fight together. Even if we lose, it doesn't matter... Our memories will live on inside others. So, even if we are born to die, I'm not afraid. I'm gonna live!"
Bold added for emphasis. My favorite line in all of... anything. Book, play, movie, video game, you name it. Such power.
