These speak of a sense of taboo.

If people use common sense and their own guiding moral compass, I think they'll generally stay out of trouble.

I'm not a victim of sexual abuse. I'm not from a broken home. I've never killed anyone before, or watched anyone get killed, not in real life anyway. I guess I am just a little bit sick. I can't help if it turns me on, both physically and mentally. I guess I just like what I'm not meant to see, I guess I just like the taboo.

Taboo,

It was taboo back then. Now it's bigger is better.

In the literary world today, Christianity has pretty well replaced sex as the present pet taboo, not only because Christianity is so often distorted by Christians as well as non-Christians, but because it is too wild and free for the timid.
