Typical WK stuff... "She's just misunderstood; nobody knows her like I do; she's actually really nice"... Trying to be a special snowflake, and ****. Sympathizing her all along the way, and not even realizing who she is. I bet she plays a great damsel / victim... All *****es, sluts, and psychos do. All it takes is the right dumbass with low self-esteem and a savior complex to fall for it.
Bad girls are experts at putting on a super sweet, innocent, harmless, helpless, victimized, never to blame, "in need of saving" act - even as they're manipulating / using / teasing / deceiving / playing / abusing / murdering people; whoring around; etc. Literally at the same time, and to the same person who is sympathizing with them. I bet she's fooling him, and is a great manipulator. Criminals and troublemakers usually know how to manipulate the mind, and put on the fake charm, and lure in sympathizers who make up excuses for them, believe everything they claim, take their side, etc... Just like any other predator.
Still, this is extreme, and he's a gullible idiot. But that's who they target, and keep around - because they're understanding, sympathetic, desperate, etc. Just another dumbass nice guy falling prey to Satan's minion.
