So What if I'm Afraid of Zombies

I may have an irrational fear of zombies. I also may have an idea of what I would do if there was a zombie apocalypse. Most likely I would die but there's only so much a person can do. I know it's not scientifically possible and it would be stupid to think about it too much but the idea of it happening really freaks me out!

How could this creepy zombie girl from 
The Walking Dead NOT freak you out!
 

I think its because I don't trust the morality of some scientists. I've seen movies where a scientist is like "hey, I wanna try this. Let's just see what happens." And then a whole ton of people die. I think science and morals kind of have to go together otherwise we're all screwed. I'm waiting for the day when a scientist is going to see if it is possible and the world will be doomed. I also have the same fear with biological weapons though so it's not just zombies. We have the ability to create some horrible things. The question is, should we? Where do we draw the line?
