A lot of DU is incoherent.

There is no way you can convince me your entire group except maybe Astarion and a Shar aligned Shadowheart won't leave you if you accept to be Bhaal's Chosen right in front of them. This is outright bonkers. You are saying in front of all of them that you're just going to be Orin 2.0, that you will use ghaik psionics to dominate and murder the world, and somehow Lazael, and the good aligned companions who would leave you if you kill the tieflings at the grove just STAY with you. That is just really incoherent writing.

Choosing to embrace Bhaal as his Chosen should cost you all companions but Astarion and Shar-aligned Shadowheart. Not even Minthara would support this decision, considering she was abducted and dominated by a Chosen of Bhaal, and she detests all gods for it.

Even at the very beginning it makes no sense. You are going to seriously tell me that you maim and eviscerate Alfira in a terrifying murder, and none of your camp mates take notice of the noises? Like what?
