Between all animals only a zombie can kill a human for power. Other animals kill for food and survival.
There is a very strong relationship among every nation and its own zombies. Every nation needs its own zombies. So it builds them and/or helps them to flourish under some occasions. By this way the citizens they remain humans with breathing vivent thoughts won't protest for a living life. Lots of zombies can kill in the name of "mama country", it's like the umbrella corporation in Resident Evil. The capital letter for words Nation and Zombie, can give a swastika, this stupid thought of mine can be a memorability game that they are the consistent parts of the same thing. I didn't mean to scare anyone. This is a message to anyone left alive.
