The killer of all fathers

Well, this is quite the name the Winter Soldier has made for himself, since he is also responsible for the death of Tony Stark's parents. If he indeed killed T’Chaka, then we might know with which team he will ally. The loss of the parents will be quite the reason for Black Panther to side with Iron Man.

But where does that leave Klaue, who was the one to kill Black Panther's father in the comics? Why would they introduce the arch nemesis of T’Challa in Age of Ultron just to steal his thunder by placing Winter Soldier as the one responsible for the death of the former king of Wakanda?

What do you think? Should we grab a spoonful of salt or trust what Umberto Gonzales has to say?
