Well death isn't just in video games, it is also in books, tv, personal life, etc... Just watch the news for 5 minutes and somewhere between them talking about Paris Hilton you will find a little death thrown in.
It is just a part of every day life so it isn't hard to see why it is not so terrible to see in a game, where at least it isn't real.
Now if you will excuse me I am going to go kill some back stabbing japs! (in SHIV of course
)
