The Walking Dead. In the first episode of The Walking Dead, Rick Grimes a police officer gets shot and goes into a coma. He wakes up in an apocalyptic world where walkers roam the streets. Rick has to kill some of the walkers to survive and even the healthy humans are turning against each other. Evil is a big theme in the series because of how normal people are faced with a choice to either do evil or die. Saint Augustine came up with the concept that there are two kinds of evil, natural evil and moral evil. Natural evil is diseases and natural disasters and moral evil is when us humans does something bad consciously. In The walking dead the walkers are natural evil but there is so many different scenarios that it 's hard to differentiate between what evil is. In a survival situation like this I don 't believe it 's evil to kill the walkers because they are already dead and wants to kill. The plot structure in The Walking Dead is Man Against Nature. This is because the walkers aren 't humans, they are a disease and they are against the rest of the living population. In the episode Rick a man alone in the world has to kill the undead to survive and since the walkers are only there because of a disease it 's Man Against Nature in my opinion. It could be argued that Man Against Man also is a plot structure because the Survivors now also has to fight each other to get supplies and survive. The world is full of natural evil now and it puts so much pressure on the humans that
