Granted, in most cases, GMs will advise you to simply leave the dungeon. Now you could argue the DPS/Healer should ask beforehand, and we can certainly debate that.
Nevertheless, when the DPS/Healer pull, they aren't intending to cause a wipe even if one occurs. A tank refusing to take aggro is deliberately griefing another player. The intent is what separates the two.
