I can understand how that might happen. I've got a number of friends I enjoy taunting by telling them the problem with D&D's alignment system is that Lawful Good is an oxymoron.
It is Just Another Fine Example of how the L/C axis and to a large extent the G/E axis are assigned to creatures/societies completely arbitrarily and are by consequence completely meaningless-- they no longer even serve their original function of marking "alignment" with cosmic forces.
edit: Though, really, Tieflings? They got a Charisma bonus and all of their iconic classes were Charisma classes... so what the Hell was up with the penalty in 3.X?
