"I don't like to use the word, but it's almost ghoulish."

A ghoul is a folklore monster, most often associated with the consumption of human flesh. The word is derived from the Arabic word ghul, "to seize".

In Arabic folklore, the ghūl (literally "demon") is a shape-shifting demon found in the desert that preys on unwary travellers and children.

The word ghoulish is used as a derogatory term for a person who takes an unhealthy interest or pleasure in the macabre, which is the meaning here.
