Is Lily J. Potter not a Horcrux victim?

Her death was the one which turned Harry into a Horcrux. It might have been accidental but doesn't it still count? 

It's a tricky one! But Lily's death did not make Harry a Horcrux. Rowling spoke about it herself, and basically what happened was that when the Killing spell rebounded and hit Voldemort, he had broken his soul so much that a piece of what he had left broke away and latched itself to the next living thing it could find - Harry. I know the spell rebounded because of the spell that was created by Lily's death, but it did not turn Harry into a Horcrux. The death that made it happen - directly at least - was Voldemort's. So I wouldn't say Lily was a Horcrux victim - she was never killed to make one and her own death did not make one, it only helped create another way for it to happen by mistake. --Kates39 (talk) 21:15, August 23, 2016 (UTC)
Thank you! That makes sense. However, if it was Voldemort's death that caused the Horcrux to be - as the spell rebounded and hit him - wouldn't he then be a Horcrux victim? He may not have died but... I don't know. Xx-connor-xX (talk) 23:39, August 23, 2016 (UTC)

However, her death wasn't the one which turned Harry into a Horcrux.

I don't think it was her death that turned Harry into a Horcrux. It happened after she died.
