Although psychologists cannot claim anything about a man they never met, they still assume he hated women and thought them lowly and worthless. The extent of this hatred was beyond limits and this is the reason why he distorted their faces in an effort to destroy their identities. According to other theories however, he was just a maniac who suffered from mental illness, which is the reason he brutally killed and butchered prostitutes, mutilating their bodies and removing their organs.
