The main point of making evil aligned characters stronger than ordinary characters is that any non-evil characters are likely to band against them, making it virtually impossible for them to win in a large-scale PvP situation.

Also, if you were referring to my character then there are plenty of reasons why a Dead Apostle master is balanced in the setting. Mostly the fact that they have half as much mobility, and the drain on their stamina is ridiculous because of their natural degeneration.
