They're one step closer to taking over....

I believe a counter argument could be made that the kid built the map in preparation of a possible terrorist attack on his school. Maybe the kid was a boy scout and just wanted to be prepared. And while Counterstrike is violent, it is not grossly or perversely violent and doesn't glorify terrorists over counter-terrorist. If anything, it promotes strategy and teamwork. I don't believe the average player even cares which entity they play as, except for if it gives them a strategic edge on a map. Have him cleared by a shrink and get him the hell back in school...
