I'll admit it's debatable but to be fair, Mark did implement an S&M fantasy into one of his kills. In its nature, that is sexual. Couple that with the satisfaction he got from torturing the victims, it is similar to the M.O. of several sexual sadists. I certainly see both sides of the argument, though.

To be fair, we make a lot of assumptions about unsubs that aren't really addressed on the show. That said I think he should be classed as he is but I'm not getting involved any further, all due respect to you both. I've had my say, if ultimately Mark is definitively removed from this category, I'll just roll with that. It makes no difference to me at the end of  the day, personally. I'll leave it at that.
