Someone please explain.....
This is skin is alright, but seems like no effort went into keeping up with lore sub-themes. . really? Of all the evil ADCS you pick her? She has nothing to do with bloodmoon Kalista or Jhinn, what a joke. Get your shit straight - probably Kaisa would have made better use of that tittle.
Stop ruining your own products by trying to sell quick skin ideas. The pizza one was clever, this one is humiliating. 
A big part of skins is to intentionally put the champion into a theme they wouldn't normally be a part of. For example, Noxus Poppy (Poppy is Demacian if you didn't know). If anything, I believe they're doing something right when they give a champion a skin that goes against their normal theme. It opens up whole new worlds. Sure, canon themed skins are great and there's nothing wrong with them, but sometimes it's nice to see what things would be like if things weren't following the normal theme.
I'm willing to bet they didn't pick Sivir to receive this skin because they thought it would fit her character, but just because they felt she deserved a skin and thought the theme would be cool for her. Personally, I think it looks pretty damn good, and I think they hit the mark as far as cool skins go.
Skins have nothing to do with canon lore of the main universe in 90% of the cases
Also: Zilean is not evil, and he has a Blood Moon skin as well.... Same can be said about Shen and Kennen and you can include Akali, Diana and even Twisted Fate in the list of "not evil dudes that have a blood moon skin".
Oh, and Kaisa is not evil as well, just saying.
Its blood noon, yee haw.
