Canon on White Fatalis?

IB shed a lot of light on Fatalis’s mythos and nature. Being the only creature in MH considered completely evil, and a lot of its lore intentionally up for interpretation on which legends are true to it.

But White Fatalis is really weird, because whereas Crimson Fatalis is a variant of Fatalis who was repelled and got very angry about it, White Fatalis isn’t even a subspecies and only shares Fatalis’s name not anything taxonomically explicit aside from a vague notion “they are related”.

Fatalis is evil => Crimson Fatalis is evil

Fatalis is evil ?=>? White Fatalis is evil

Because if White Fatalis is NOT Fatalis, then it’s a genuine question if we are to interpret its something completely different.
