To me it seems mostly: We don't know enough about their motivations yet.
And I suspect there's a link between "Snowflakes" as you put it, and True Souls
There is a goblin reading Volo's book at their camp outside the temple at the top of a "tower". He says a few interesting thing about being chosen to be a True Souls,
including that only people with lots of "magical power" are chosen by the Absolute to become True Souls.
