Gollum The Hungry Ghost

Gollum in ‘Lord of the Rings’ in pursuit of the One Ring
is almost the perfect personification of a hungry ghost.

Consumed by greed, his essence of being is nothing but craving,
at the expense of everything else, including his life eventually,
as he plummets into the lava of Mount Doom while reaching for it.

The mountain didn’t cause his doom.
His craving did.
