I know exactly what you mean, Sweet2th. The other day, as a distraction, I played some UT. I was apalled to see that a few members of one team had one guy from another team pretty well trapped. When they didn't immediately kill him, I felt a warm tingle that I think was hope, and love for mankind. Obviously, they all knew that they had him, and the jig was up. I figured they'd chat, have a cup of tea, and let the poor guy go.
Imagine my surprise when didn't let him go, but instead, shot his head off. SHOT IT CLEAN OFF ZOMG WFT ??!1!?! I was sick to my stomach, and cried for hours afterwards. It is apalling to see how far we've regressed when it comes to violent games.
