I think that you're perspective is not fully correct. If a duergar makes a role that he wants to become a paladin would that not make it legitimate to ignore his alignment based on his role?

Should all the maran be turned evil because they like to kill neutrals and evils alike ?

Should a neutral warrior be turned good for killing evils ?

Should a evil be turned good for only killing evils ?

Where do you draw the line for any character and their actions, that is what is always unclear and often creeps up on players who do not understand the area in which the lines fluctuate.

Gataliff without the infection, role wise, was actually more good than neutral. All she did was run from fights and help people with her prayers. One of her lust's was that she liked to watch combat, but not participate. That lust was so that she actually interacted with the player base instead of avoiding it. A healer that hates fighting and avoid it at all costs is a character that has nothing to do with the game and gets bored very very quickly.

So on one side you have a gnome that leans heavily towards good, very heavily. On the other side you have the blood of a demon-god. The god of annihilation and destruction.

The hand, the infection, that was the aggressive side of gataliff never cared for alignment or ethos or anything really. As long as you brought destruction to the realm in any form it was happy with that. Goods killing evils was just as good as evils killing goods. Hunting evils was just as good as hunting goods. I think my pk's, the few I have will display that.

The few times I grouped up with people was when the odds were against them, 1 vs 3, I would make it 2 vs 3. Two clear cased come to mind, both grouped with evil. The first I and said person were ripped apart by the group of goodies. The second time I and second person managed to kill 1 as the rest ran away. I rped pleasure under both circumstances annihilation and destruction had come. Even if I was the one being destroyed.

The player base has more evils and neutrals and this made it harder if anything to killing more goods as the hand. But I never choose a side. Anyone who wanted my prayers for a pk or a raid or a uneven fight had them. Regardless of alignment or cabal.

The only aspect role wise and action wise that I was doing that leaned me towards evil was that the hand, the infection, was the blood of a DEMON-god. Evil in substance.

I really do hope that was the main factor for turning me evil. I would be vastly disappointed if I was turned evil because I grouped with a few evils, or killed a few goods.
