To me a Bad player isn't someone who tries but rather the opposite. We all have off days or are new to something now and then and the stress level amps up when it seems like somethings going wrong. A Bad player is someone thats overconfident in thier abilities and wind up being far too lax in thier approach to thier role to the point that they will wall to wall pull and due to that lose aggro because their healer has to spam cures and sheilds like no tomorrow and then when the healers are low on mp go and pull more to the pile.

Lets not forget the healer that over DPSes and loses track of healing this happens alot more often than people think it would.

And then theres the DPS thats in such a rush that they wind up facepulling more mobs thinking the tank and the healer will pick up the raid pass often not realising that the tank is past thier safe limit or that the healer is running low from bad healing choices.

Not only these things but these selfsame players then have the gall to start berating and insulting other players usually sprouts for not doing it right. These are bad players noone else.
