First of all. New account cause I tried to reset my old password and the link just takes me to the mmo forum main page. Old name is Ardac. Not a lot of post, mostly a reader.
Second, actual lore question. I know lore can and has changed and let's ignore our own general dislike for characters.
So on to the topic....
Another death brings another soul to Bastion for judgment, unlike others that have lived with their own choices (good or bad) you are now flooded with souls that seem to be tainted and scared. Among these would be the forsaken, Sylvanas, Arthas, the death knights, and more. Some, he pre forsaken undead for certain had no free will with the idea being they were simply undead husk. But back in wraith we went undercover as a ghoul and interacted with other ghouls and whatnot.
So, assuming lore is what is above. Should these souls be judged based on their actual first death and who they were in that life or their altered existence?
Arthas in the afterlife video is one example, Sylvanas is another. Both can be seen as heroes in life (Arthas was going mad at the end yes), but in undeath did truly evil things.
This isn't a question for how the game will handle them as much is how would you personally handle them if you were their judge in the afterlife. The names don't matter, I know Sylvanas gets a lot of love / hate. For this simply look at the person she was in life vs death.
