Sorry, have you failed to distinguish between reality and fantasy? Granted I maybe should've said it sounded entertaining instead of enjoyable given the potential for sexual connotations but can you not see that it's to be read as fantasy and not as a guideline for an action in reality?
I'm willing to bet that at some point in your life you have played a game that has resulted in you killing some other form of "life" in the game and that it brought a smile to your face. Shall we recommend you for psychiatric assessment too?
You have also got your definitions confused, if something is "illegal but unprovably so" then it must therefore be legal. The Law does not set out what is legal, it sets out what is illegal and so if it doesn't fall into the "illegal" category it must therefore be legal, not the other way around.
The guy is not doing time for it (mercifully) because he has a fundemental right to be able to compose and publish works of pure fantasy. Is everybody really a boring mindless drone in your utopian world? What this guy did in writing and publishing his story was 100% ok and I'd hate to live in your world where it seems it's not.
