John specifically seeks out prostitutes because he believes they are the most corrupted women he can find, referring to them as the 'evilest'. His ritual sacrifices to the Aztec goddess Coatl require victims he considers morally depraved, making prostitutes his preferred targets.

Foreshadowing: Early in the film, John explicitly tells a bar patron he is looking for the 'evilest' prostitute.

John performs an Aztec sacrifice ritual dedicated to Coatl, which he describes as the 'queen of evil'. He ties his victims to a table, eviscerates them, removes their heart, and offers it on an altar. The ritual is repeated multiple times throughout the film, with John dressing in a robe and metal mask during the ceremony.

John hesitates because he senses Sissy's 'inherent purity and lack of corruption', which contradicts the type of victim he typically seeks for his sacrifices. Despite his usual methodical approach, he initially orders her to leave, though she remains unaware of his intentions and insists on completing their transaction.
