I had a guy at work ask me that question the other day. I told him of course, I can't speak for anyone but myself, but for me, It allows me to shoot at a human-like target, without feeling like I am shooting a human (even if its only a paper target). One of the perks I have at work is a large scale plotter, meaning I can print life size targets from online. OK, I do have some police-style targets, some of the conventional bad-guy with a gun. People get bored shooting the same old target, least I do, so a nice collection of killer zombies fills the bill.
