I don't really think the Arrancar that appeared in this chapter are really "dead", because they seem to retain some form of their former personalities, like Mohrpheus mentioned below.

For example, Dordonii and Charlotte are doing that weird stance that they did when they were alive. Perhaps, they still possess some consciousness and are not just mindless zombies.
