I'm thinking the whole true soul being chosen thing is bs, especially if Minthara doesn't have a tadpole.

Sofar every true soul we have seen has essentially been a battlefield commander, with Minthara pulling the strings.

Maybe the True Souls are just ment to be Leutenants led by a Cleric of the Absolute which lacks a tadpole, making it easyer for them to sneak in and convert a populace.

Gut for example refuses to believe she has a tadpole and is driven to kill you in secret if you tell her
