No. She clearly fails the heinous standards established by Bill Cipher.

Also Bill Cipher is actually the worst monsters to appear in the show, since he destroyed his own dimension and intended to do the same with our universe. His death toll would have risen up to trillions of lifeforms, while Anti-Mabel is "merely" a murderer.

Also, it seems that lots of people don't take her seriously. I personnally don't know since I'm not that interested in Gravity Falls.
