The warrior role trades willpower benefits for expressions of pain but does that mean inevitable, unexpressable repression en masse?
It's been said that the world is shaped by two forces - the will and imagination. Sometimes these are at odds with each other. When somebody tells you that the warrior role is all about will power, you're not talking with a strategist.

I don't know, but people who repress pain don't express it en masse, they express it creatively. It is unlikely that the expression of pain would lead to a repression en masse. Traumatic pain has a just cause, therefore justice is not impaired, there's still a deeply ingrained sense of justice. It's also difficult to categorise individuals collectively.
