On Blasphemy and What's Worse

It's odd that patricide and parricide should both be words. But what I am still wondering -- indeed, what keeps me up nights -- is, what do you call somebody who kills his paternal grandfather's cousin-by-marriage?

--Percy



Parricide--killing one's father or mother or other close relative
Patricide--killing one's father
Matricide--killing one's mother
Fratricide--killing one's brother
Sororicide--killing one's sister
Filicide--killing one's child
Mariticide--killing of one's husband
Uxoricide--killing of one's wife
Deicide--killing a god

The way we have families these days, it isn't even necessary, for instance, to kill your wife--you don't need one (in order to have children) to start with! Moreover, no need to kill the child, we can just prevent their birth. This reminds me of Eliot when he writes about blasphemy in After Strange Gods:

"[B]lasphemy is not a matter of good form but of right belief; no one can possibly blaspheme in any sense except that in which a parrot may be said to curse, unless he profoundly believes in that which he profanes ... It is certainly my opinion that first-rate blasphemy is one of the rarest things in literature, for it requires both literary genius and profound faith, joined in a mind in a peculiar and unusual state of spiritual sickness. I repeat that I am not defending blasphemy; I am reproaching a world in which blasphemy is impossible."
