"Maldoror" - bornwicked

From Project Gutenberg:

J'établirai dans quelques lignes comment Maldoror fut bon pendant ses premières années, où il vécut heureux; c'est fait. Il s'aperçut ensuite qu'il était né méchant: fatalité extraordinaire! Il cacha son caractère tant qu'il put, pendant un grand nombre d'années; mais, à la fin, à cause de cette concentration qui ne lui était pas naturelle, chaque jour le sang lui montait à la tête; jusqu'à ce que, ne pouvant plus supporter une pareille vie, il se jeta résolûment dans la carrière du mal ... atmosphère douce!

Comte de Lautréamont (Isidore Ducasse) - "Les Chants de Maldoror" - 1868-69

Via Google translate:

I will state in a few lines how Maldoror was good during his first years, where he lived happily; it is done. He then perceived that he was born wicked: extraordinary fate! He hid his character as long as he could, for a great many years; but, in the end, because of this concentration which was not natural to him, every day the blood rose to his head; until, unable to bear any more such a life, he threw himself resolutely into the career of evil... a sweet atmosphere!

My own synopsis:

I will state in a few lines how Maldoror was good during his early years, when he lived happily. There, done. He later realized he'd been born wicked: a strange fate. He hid his character as long as he could, but in the end he acknowledged the truth and admitted he was evil.
