However, it is you who have influenced me to be somebody who holds to this like a sacred trust. You really have been a good influence on me.

Even though you have a cat.

I feel that entries 8 through 14 speak for themselves. So let us turn now to chthonian, which offers a rich shade of meaning to the definitions given above:

“of or pertaining to the deities, spirits, and other beings dwelling under the earth.”

Whether there are deities or spirits dwelling under the earth such as Hel and the Svartalfs of Niflheim, Hades and abducted Persephone, or Satan with his retinue of demons, is a matter My Lady will have resolved for herself, but I wouldn’t loan money to any of them. Likewise worms, serpents, scorpions, moles, “and other beings dwelling under the earth” aren’t generally regarded as wholesome or benign (however they may taste with garlic).

Finally your cluster concludes with animalistic:

“of, relating to, or resembling an animal or animals; brutish”

Brutish, My Lady. Brutish. And all this followed immediately by My Lady’s reminiscence of her attempted rape!

I would write more, but the latest product of my dark, chthonian, animalistic lusts is cranky, and though he can’t talk yet, he threatens to smash the keys if I don’t put on another episode of I Dream of Jeannie to distract him. I suppose I must admit that he is indeed a little brute.

Many (most) young boys have had the living %*%@ beaten out of them by other/older boys, terrorized in various ways.Multiply your experience in intensity by about 20-fold, and repeat a dozen times, and you have my boyhood. Big deal.

Males are overwhelmingly the victims of male violence, and the victims aren’t always the ones who go looking for it.

And yeah, it means “of the [deep] Earth,” not “evil.” When teamed up with “dark” and “animalistic,” it does rather suggest “the dark side of nature.” But it also suggests “primal,” perhaps “elemental,” but that’s not quite it. Or maybe “deep, dark, and mysterious.” The sort of thing from which both good and evil spring, rather than being good or evil itself. I suspect that this is what you were going for.
