For what it's worth, I thought it was bugged, too, but it turns out you just can't kill Einar. Einar is the one who tells you how to use the cursed fang. If Geralt kills him, Geralt never learns what to do with the cursed fang, so Geralt's only option is the feeding-him-part-of-himself one. If you don't fight Einar, he tells you about the fang, and then you get the option of using it. Not sure if that's the solution to all your problems, but that was the solution to it, when it wasn't working for me (i.e. using the necklace to break the curse wasn't showing up as an option).
