Man! You guys are turning me into a defender of Larian because you're going a bit to the opposite end of the spectrum.
This is EA. We're only in Act 1. Give Larian a chance to explain things more. Of course there are things that seem like plot holes, and if we had the whole game and they never explained anything, I'd be in total agreement with you. However, we're in Act 1.
And it IS explained by several people that we have VERY special tadpoles. So special that a cambion wants it for himself. Does he want Minthara's? Nope. Does he want Ragzlins? Nope. Just ours. Ours is a catalyst. It is given authority over other True Souls even. It is a boss tadpole protected and imbued with Sharran/ Netherese Shadow Magic which is keeping it from turning us instantly into mind flayers - or whatever it will actually turn us into. It is even said by Omeluum that whenever we do turn, it will likely be far more excruciating than any other ceremorphosis ever, and it has burrowed so deep into our person that he cannot remove it from us either via connecting mentally with it or by physical or magical means. It is apart of us completely.
People, this is no different from Bhaalspawn. Instead of being infused by the seed of a god, we've been infused by the seed of mind flayers - a special mind flayer seed that has made it apart of the very essence of who we are. It is really no different. We have been reborn as something new and godlike, and it is very different from any other mind flayer parasites ever, including that of other True Souls. THAT is why the Absolute wants us so badly, not just the weapon. THAT is why Shadowheart is called a beautiful weapon by the voice on the ship. We are MORE than any other, and the tadpoles can't be crushed and removed and us resurrected because they ARE apart of us now. If we are rez'd, the tadpole is rez'd with us.
