I consider it a must-read for anybody who is interested by litterature.
But I don't really get what you are trying to say.
Well, the "hero" of the novel murders over 20 women, doesn't he? It's a story about a serial killer. And yet it's a story about a sort of person who does not exist. Serial killers exist, but no-one remotely like the hero of the novel exists.
I would never read a novel where the hero was a serial killer in the first place, but if I did I'd want it to give me some sort of insight into that sort of person, but in this case it's a made-up sort of person, a sort of person who has never existed.
As for being interested in literature ... one gets to pick and choose.
You have never had the pleasure of hearing me read
Fern Hill, or
Ode To A Nightingale, or
Waking Early Sunday Morning, or
Spain ... I shall say nothing of my own poetry ... so don't tell
me that I'm not interested in literature unless I read a book about a serial killer. There are other things to do.
Literature apart, here's
Murray Perahia playing the Goldberg Variations. Why should I have to spend a moment of my time thinking about imaginary serial killers?
