(will try to avoid spoilers)dads plan was just to help other people with wakanda tech, but the Villains plan isn't helping, his plan is the destabilisation of wakanda and the whole world(they repeat this like 3 times in the movie when talking about him) also this is shown symbolically in the burning scene, he did that because when he's finish, wakanda and the world are finished.
edit: also a wrench in his plan would be telling the truth since the military wouldn't follow a traitors kin, they are faithful to the throne but more to wakanda, why would they follow someone who is kin to a traitor?
ok I will stop now I think this is getting a bit long for really was just something that bugged me about a really good movie I'm just gonna move on now
