We also don:t kill massive amounts of people either like we do in game but noone is talking about that are they?
The difference is that the people you kill in the video game are NPCs. I promise you, if you went around killing massive amounts of people without their consent--it'd be quite a big issue. Even PvP REQUIRES consent to participate. You can't PvP without queuing up for PvP, and in a lot of games--you have to specifically flag yourself for world PvP. It's very rarely something that ever happens randomly to people who don't consent to it.
