Nah, it's not implied. The whole point of the movie is that those with need for revenge will find a way to get revenge. Now, vernita deserved to get axed...or knived... but nikki did nothing wrong. She just had her mommy killed in front of her. By Tarantino standards, she'll kick the brides ass all over the place. thats my theory anyway.

and ona side note, come on man, the name was beeped through a movie and a half, don't jsut chuck it out there like that. spoiler tags please.
