Well, it's either that or dying as per the current quandary. To twist Dark Knight - You either die and stay dead, or live and possibly wish you weren't. In the latter case, well, I don't think End's found a way to collect on debts in the afterlife yet, so the first is always an option after taking the second, ergo you'll always want to be revived.
Plus, you wouldn't be a zombie so much as a Ghost in the Shell as in Ghost in the Shell.
