[Doctor-X] Isn't Jeon Kuk-hwan an organ trafficking broker?

Instead of running a medical volunteer organization in Cuba,
I suspect he was actually bringing children in to broker organ trafficking,
and when he got caught, he tried to burn everything down to escape, but almost died himself.
Even in the scene that seems to be a flashback for Cho Won-jin,
when he says "Dad is a monster,"
it feels like he was committing some massive crimes.
That might be why Cho Won-jin uses the surname Cho instead of Kim.
And while the intern's childhood is definitely connected to Jeon Kuk-hwan's misdeeds,
if we're talking about the writer's potentially thin imagination,
I suspect it might be child organ trafficking.
