In many forms of media, if zombies are present, there will be an infected that wants to die as themselves. Some go to far lengths to keep themselves from turning.
So! If you were infected, would you want to die as a human or try to hold out for as long as possible? If you were bitten, how far would you go save yourself? (Cutting off a limb, attacking a military convoy that might be holding a cure, etc).
Of course, you probably couldn't tell how far you were willing to go unless you were actually in that situation, but no reason you can't think about it.
