Translations for everlasting in French

Here are paragraphs from public domain books translated:

Is there anything sadder in the world than the old age of vice, especially in woman? She preserves no dignity, she inspires no interest. The everlasting repentance, not of the evil ways followed, but of the plans that have miscarried, the money that has been spent in vain, is as saddening a thing as one can well meet with. I knew an aged woman who had once been “gay,” whose only link with the past was a daughter almost as beautiful as she herself had been. This poor creature to whom her mother had never said, “You are my child,” except to bid her nourish her old age as she herself had nourished her youth, was called Louise, and, being obedient to her mother, she abandoned herself without volition, without passion, without pleasure, as she would have worked at any other profession that might have been taught her.

En effet, quoi de plus triste à voir que la vieillesse du vice, surtout chez la femme? Elle ne renferme aucune dignité et n'inspire aucun intérêt. Ce repentir éternel, non pas de la mauvaise route suivie, mais des calculs mal faits et de l'argent mal employé, est une des plus attristantes choses que l'on puisse entendre. J'ai connu une ancienne femme galante à qui il ne restait plus de son passé qu'une fille presque aussi belle que, au dire de ses contemporains, avait été sa mère. Cette pauvre enfant à qui sa mère n'avait jamais dit: tu es ma fille, que pour lui ordonner de nourrir sa vieillesse comme elle-même avait nourri son enfance, cette pauvre créature se nommait Louise, et, obéissant à sa mère, elle se livrait sans volonté, sans passion, sans plaisir, comme elle eût fait un métier si l'on eût songé à lui en apprendre un.
