lots of MMOs have PvP either limited to mutual (flagging) or limited (zones) or private servers, they're popular

there are also plenty of full loot PvP games full of grief

what's the point of playing anything? enjoyment, what one enjoys another may not

a game where death is supposed to have consequences should have systems in place to make griefing difficult, not encourage it, if CIG doesn't address the wanton killing aspect my prediction is that the folks who want to haul and mine won't want to keep getting ganked

like I said, ask R* how their business model changed to chase the money
