Wouldn't you enjoy that vaguely dirty and disgusted feeling afterwards then?
Well, since Canderel didn't answer your query, and that this a thread where people ask questions to ME, I'll answer it myself.
I have fantasies where I want to be some final boss fighting against the protagonists, who defend the world which I want to destroy because I'm evil incarnate, with a kick-ass music theme, HP up max, ultra-hard difficulty (I AM hard), special moves with OTT animation that lasts for nearly two minutes, and to be able to ask inquisitive phrases, such as "...Why do you defend this world?" or "Don't you realise that your efforts are futile?".
Dirty and disgusting because it's an uncanny video-game geek fetish, but I love it.
