I thought this question a couple of times and thought, maybe zombies aren't bloodthirsty for brains, maybe they are jsut really confused (I am talking about a REAL ZOMBIE and not one like in the last stand or anytihing). I mean, if I woke up fromm a bloody pool witha knife in my forehead I would first go into a panick and then with my heightend abilities I would probably go into a rampage just being a torn up piece of ability crushing everything in my way due to the complete confusion and realazation of my life as never seeing my family again without them seeing me as a bloodthirsty monster making me mad as heck while probably venting out feelings with pouring out what's left of tears till I eventually get tired of it all when I start to bleed blood and finnaly realize after I killed /destroyed many things and/or people that I could not "live" with myself anymore thus going into a spiral of regret, rage, sadness, which would be the "moaning" zombies do from all the bad things they are actually conciencous about. . . Then I would search the world either in a tyrant or triying to find a way to kill my undead self.
If zombies even were real if you hit one it would fall apart because all of it's muscles and tendons are rotting and the bones are holding on by just a thread.
