Confusing Quote

"We are accustomed to look upon the shackled form of a conquered monster, but there-there you could look at a thing monstrous and free." Pg. 108
The rest of the paragraph also make references to a "monster," but what exactly is this monster? Is it human? or something darker? It is unearthly but does that necessarily mean its not of this earth?

Juicy Quote

"The fascination of the abomination you know, imagine the growing regrets, the longing to escape, the powerless disgust, the surrender, the hate."
Very obviously juicy as it takes a deeper look at human emotions and the obsessiveness of a fascination.
