I think Kim Jong Un ordered his half brother's death because he was afraid
that his half brother, Kim Jong Nam will steal his throne. The rule of North
Korea is this: the eldest is the leader of a group. Anyway, Kim Jong Un's father was mad at Kim Jong Nam because he used a fake passport to go to Japan with his
family. I think Kim Jong Un heard about this thing. He plan to kill his half brother using this incident and took his chance, so he ordered his
subordinate to make VX, and kill Kim Jong Nam.
Hello, Michael, please be careful with the facts that you write. They went to Japan and not to China. Also, the name of the North Korean leader is Kim Jong Un.
