Exactly as I pictured him. He's someone fatherly, quiet, almost meek. A pillar in the community, probably goes to church with his wife and kids, maybe even holds a position in his church. And that world is extremely important to him. That's why I don't believe he dismembers or keeps bodies. He's compelled to kill, but once the deed is done, he's desperate to distance himself from the act emotionally, otherwise, his worlds begin to collide.
I'd also bet there is somewhere other than home where he takes these women...a nearby hotel, a private boat, perhaps an office (if he owns a business).
all just MOO
