4. Hypocrisy
One of the most shocking aspects of Call of Duty is the ridiculous, pathetic level of hypocrisy on the part of players, and something that pretty much nobody is exempt from. Think of all the excuses you can possibly complain about; a player was camping, he's a quick-scoper, he's using a noob tube, he's got a lag compensation boost, he's using martyrdom, he's spawn-camping, or using an apparently egregious combination of perks. There are countless things people will whinge about, no matter how clean a kill is, and the worst thing is that we'll all decry such techniques in the brief moment of post-death rage, but we're more than likely do some of these "lame" things ourselves. Who among us has never used the noob tube? Who has never camped or used martyrdom? Let you be the one to cast the first stone, but I doubt there'll be anyone around to do so.
