Uhh...well, let's look at the logic here. We have three characters: Jeff the Killer, The Slenderman, and Ben Drowned. Here's an evaluation of the characters: Jeff the Killer is a male human serial killer, who is also insane, and goes on killing sprees for fun. The Slenderman is a myth originally made up to scare small children from going into the woods. And Ben See More Drowned is a glitch in a haunted Majora's Mask cartridge who follows the main character around. All of them are in separate universes, and have absolutely to motive to go around being shipped. As a matter of fact, part of what makes some of these creepypastas creepy is the fact that they don't feel emotion, including love. No reason behind the murder, no face behind the mask. Seriously, though. A lot of creepy pasta wear some sort of mask, or did something to make themselves unrecognizable.
And then you wonder why he kills people!
