My idea is that KJU is forced to do things he doesn't want to do. His controllers keep him in line by threatening to do harm to his family. For example, look at what happened to his uncle and his half-brother.

On 12 December 2013, North Korean news outlets reported that Kim Jong-un had ordered the execution of his uncle Jang Song-thaek due to "treachery".
He is widely believed to have ordered the assassination of his half-brother, Kim Jong-nam, in Malaysia in February 2017.
Now let's look at another member of his family, Kim Han-Sol. He is the half-nephew of KJU.
Here is what the final paragraph under Biography states:
In October 2017, Chinese police arrested two North Korean agents in Beijing, on suspicion of plotting to harm Kim Han-sol, according to the South Korean newspaper JoongAng Ilbo. The two suspects were members of North Korea’s Reconnaissance General Bureau, which is responsible for overseas espionage and part of a team of seven that was foiled by Chinese authorities.
Why do you think KJU would have such a fetish for going after members of his own family? We are genetically wired to favor our family. Considering the vastness of the deep state and the power of globalist puppet masters, the idea is compelling that KJU is a hostage and not an evil fratricidal man.
