This Japanese man is not that twisted as you may think. It's rather simple. The only thing that's different from us to him is that he had an intense loveual attraction to eating beautiful women. It makes sense really. It's like a step up from love. Imagine if there was a next step up from loveual relief than love itself. Like for us it's usually procrastination and the next step up would be love and that's it. Well in his case there was another step up from that which was eating them. Ever notice how he ate the butt first? I find butts loveually attractive, well so did he but he wanted more than just to stick his snake in it. He wanted to consume it, that's how much he wanted it! That's the way I think of all this. I'm sure it was genetics since he was born prematurely and seemed to have a normal Japanese childhood.
