YMMV / Criminal Minds S 7 E 2 Proof

• Complete Monster: Ben "Cy" Bradstone is a mentally handicapped man who uses Obfuscating Stupidity to lure women out of the public eye and into his shed, where he rapes them and then stabs them to death, with said shed containing tapes showing countless more victims. He first stabbed their eyes out, but later evolved to using sulfuric acid to burn away their senses, choosing the sense depending on how they reacted to him. He targets women who remind him of his sister-in-law, whom he attempted to molest when they were both teenagers. When his niece puts on the same homecoming dress her mother — said sister-in-law — wore, Cy kidnaps her and burns her hands. After his arrest, he tells his brother Matt, who demanded to know why Cy did this, that he has always hated him and was planning to deafen and then kill him one day.
• Diagnosed by the Audience: Exactly what is Cy's disability is never made clear. He was deprived of oxygen at birth, so possible brain damage, but his psychopathic tendencies are not explained by that, and he often plays up his disability for sympathy.
