[8] But though we, or an angel from heaven, preach a gospel to you besides that which we have preached to you, let him be anathema. [9] As we said before, so now I say again: If any one preach to you a gospel, besides that which you have received, let him be anathema. Galatians; Chapter 1

Yes, therein lies the difference between a "bad" pope and a "heretic" pope. Bad popes still deserve our obedience because they still teach and preach the Catholic Faith. A heretic "pope" does not. In fact, a manifest, heretic pope that teaches and preaches to the universal church heresy is outside the Church and therefore no pope at all.
