Expansion speculation...

[HeroSamson]

While Dark knights are commonly depicted as evil some concepts of Dark Knight follow more towards them being people with good intension but dark methods to get things done.

The Evil idea of Dark Knights is commonly due to the class/job using Darkness as a Weapon and basic generic stereotype idea is Darkness = Evil and it often leads to them going evil due to this belief.

However, Dark Knight that follow a good path have a slightly different concept of darkness being that Darkness is simple another side of Light. Due to this these types of Dark Knight remain good but their methods can sometime be a bit extreme.

Its why I said to fight my good side to turn a little evil but keeping my sanity.

I do hope the dark knight armor is really cool looking.

Well that the thing about Good Dark Knights.

Rather than fighting a Good part of themselves like a Evil Dark Knight, the Good Dark Knight Trial is commonly a battle against a dark side of themselves that they have refused to accept which is commonlly the Dark Side that makes them question if they can truely do what is necessary to save people.
