All these stupid and racist confessions about Black Panther and trying to downplay the character and kill the hype is beyond old. He held back the cure for cancer? Well guess what happened when Norman Osborn got his hand something similar he turned it into a virus, Wakanda is aware of the evils that come along with international interactions with other countries. Lets say he did hand over the cure for cancer, then they will want vibranium and probably use it for nefarious purposes. Reed Richards, Dr. Strange, Tony Stark are more than capable of coming up with a cure for cancer instead they used their power and wealth for starting a Civil War not once but Twice and shot Bruce Banner into Space cause they thought he was too dangerous. Now who abuses their power again? And don’t even get me started on Scott summers sins against the x-men.
