They're not people you know or who care about you cusack! They're online who-knows-why? Just playing games is not likely the "only" reason, they have their own lives they're avoiding or taking a break from and it could be they're taking their frustrations from their own lives out at you, just "picking fights" with strangers because it lets off steam and doesn't mean anything to them so they don't think about how they might be hurting you?
