All is not lost; the unconquerable will, And study of revenge, immortal hate

 

ミルトンの『失楽園』で、神と天使の軍団に負けたサタンがデヴィアンツと同じセリフを言うんですよ。『エターナルズ』と『デビルマン』の設定が似てるのは、どちらも『失楽園』が元ネタだから。 https://t.co/C3GkeG9vkM

Critical Essays Major Themes in Paradise Lost

Paradise Lost in Modern English

All is not lost—the unconquerable will,		Nothing is lost, I still have my free will
And study of revenge, immortal hate,		my revenge and hate
And courage never to submit or yield:		my courage to never to give up
And what is else not to be overcome.		I still have all that! What did Heaven win?

ここらへんのことを言っているのかもしれないね。
