They say great times make great men. I don't buy it. I saw a lot of weakness, a lot of filth. People who should have risen to the challenge and either couldn't or wouldn't. Greed, fear, stupidity and hate. I saw it before the war, I see it today. [...] I don't know if great times make great men, but I know they can kill them.

But no matter what happens to the surviving humans, there will always be the walking dead.

I think the general anxiety of the 1960s - '70s spawned our interest in the living dead. When people worry about the end of their world, they need a safe vessel for all their fears. Zombies provide that vessel because they're 'safe.

Zombies will try to scale any surface no matter how unfeasable or even impossible. In all but the easiest situations, these attempts have met with failure. Even in the case of ladders, when simple hand-over-hand coordination is required, only one in four zombies will succeed.

We relinquished our freedom that day, and we were more than happy to see it go. From that moment on we lived in true freedom, the freedom to point to someone else and say “They told me to do it! It’s their fault, not mine.” The freedom, God help us, to say “I was only following orders.”-World War Z

I think that most people would rather face the light of a real enemy than the darkness of their imagined fears.

Generation Z, they cleaned up their own mess.
