Someone today asked me about the name Loki!
I told him that he shares it with a giant named Utgard-Loki.
This probably demonstrates that Loki has more in common with the race of giants than he did with the gods.
I do like Loki, he can be amusing at times, though mostly he comes off as scheming and a little malignant. (And his children include Fenrir and Jormungandr, as a statement to what he's like.) Certainly not someone I'd name my child after.
When I first read American Gods by Neil Gaiman, the instant I read Low-Key Lyesmith (Loki Lie-smith)'s name I fell in love with it.
So yeah, chances are good I'll name something after Loki. Not necessarily a kid though.
In some cultures, they used to wait until a child had been around for a few years before they names them so that they had a chance to observe the child and give them a name that fit them...these are magickal workings in that when you name a thing, it will begin to take on the attributes that the name carries...so the kid named Loki, will in time begin to take on the attributes of Loki...
No, I would definitely not name a child Loki. Loki is to be respected because he is blood-brother with Odin, and his "tricksterism," while not always pleasant, is a necessary part of the functioning of the cosmos. But Loki is a force of chaos, and I would not want to burden a child this way. I used to have a German Shepard named Fenriz though.
