Q) who said this

"I have saved him. He was a man who craved power. And great power he had, but he feared losing it. Trembling at unseen enemies, he spent his days scheming petty schemes. Chased by his fears, never knowing rest. You see... Now he has no worries. He has been granted sleep eternal. Death is a sweet slumber. All the pain of life is gently swept away... Ah, yes. Don't you see...if all life were to end in Spira, all suffering would end. Don't you see? Do you not agree?"
