We see more of Datu's religious side. He refuses to do the deed himself because of the unforgivable nature of suicide. He has even put thought into to his situation. He wants to die BEFORE he turns and not after. It seems that, with the exception of Tommy, zombies are not able to make this and carry out this decision. When Micheal suggests that Datu do it himself, he says that he can't. I think Datu came to this conclusion by comparing his knowledge of his impending horror to the knowledge of any other impending hardship. If it is a sin to commit suicide because you feel that you cannot endure an illness, grief, poverty or any other hardship of the human condition, then turning would fall into this category.

I've thought about what happens to one when they are turning and whether it would be best to die before, knowing that your death is coming, or die in a blaze of glory afterwards, when it seems that you're no longer rational and full of rage. What goes on in the minds of the turned? How much of their humanity is left? By humanity, I don't mean simple compassion and decency, but the self awareness that is at the center of one's consciousness. Are you trapped inside, watching yourself commit gruesome acts? Are you repulsed by the things you do as if some other agent has control of your actions? Stuffing human flesh down your throat as if the gears that connect your free will to your means of acting have been stripped, and your limbs are dangling from marionette strings controlled by some internal puppet master.

Are you simply gone?
