But now into deep Ninjago afterlife philosophy:

When a Ninjago character dies do they become a ghost? When Morro died he became a ghost and his body was left behind. Obviously not everyone is sent to the cursed realm when they die, why else would there be the underworld? The cursed realm is a form of the afterlife, but it is not a "Hell". Morro was free to roam the cursed realm and help plot the overthrow of Ninjago. He was not being punished.

Anyway, whatever sent Morro there when he died must've sent Clouse there when he died, whether it was spells or something else.

Also, Sensei Wu said Clouse escaped the cursed realm before it was destroyed.
