Some of you might think that's great, but is it really. Is killing really that great a thing? Is seeing a fellow human's head blown off something to be enjoyed? No, I would venture to say that it's not, and most who have been in such a battlefield could tell you the same. Some call it "Mature" content, but is it really. It is indeed content for advlts on a battlefield, but not something for enjoyment.
These kinds of games are required to be played by military men for one reason. In the past during times of war many soldiers died before ever shooting their guns. Why is that? Because they understood that was another human on the other side of that barrel, with family. Because they had a moral hesitation. These kinds of "games" are meant to suppress that reaction, it's called desensitizing.
Personally I didn't mind killing in past TES because they weren't real and there was no way I could consider them real, but when you make a game with that much realism and that much gore you are allowing yourself to get used to it. I believe there is a moral obligation on the part of the DEVs and the part of us players, to remember to have respect for human lives and to try and keep at least some of our "humanity" intact.
