To expand on my final closing idea: it is not that the Warrior has any more power for destruction than the Destroyer does that makes them more dangerous when they fall to their Shadow.

It is that the Destroyer will destroy themselves, while the Warrior seeks constantly to strengthen themselves. This pursuit of strength, paired with nothing other than an agenda of pursuing further strength, leads them to attack all barriers to their own metamorphosis.

They turn their mind toward unfit purposes and become elitist and ruthless, viewing others as an inferior and lesser species. Their own self-perfection drives them past the boundaries of what they consider human, and they become God in their own eyes.
