The short answer is yes, as far as I’m concerned. A successful and talented enough writer could write from the point of view of the most despicable character and be praised for it. Being a big name in literary fiction affords you that freedom.
Myself, on the other hand, would avoid writing a first person narrative of, say, a sociopath. Certainly anything more than a few thousand words would become unbearable. I wrote one short story about someone who planned to commit an atrocity, and doing so in the first person made it a more interesting if not powerful narrative than how the idea originally came to me. But it felt risky, making it seem personal.
Few people nowadays at least under the age of 50 would have any qualms about playing a game from the viewpoint of a killer, even if that character is a brutal drug-dealing gangster. Although I’ve played many a 1st person shooter I haven’t played the GTA games but I can see the appeal: it’s a chance to be transgressive in a controlled and safe way. Maybe it’s even a safe outlet for that darker inner self. The same could be said for those who write crime or horror fiction; it’s perhaps a truism that they are considered to be the nicest and most well adjusted people.
Yet I always harbour a concern that writing through the eyes of a warped or nasty character would somehow reflect back on me as an author. After all, they say write about what you know, which often gets interpreted as write about what you have experienced. And of course, we don’t live in a bubble; life must have some influences that come through in the work. But if actors can play at being bad without the consequences then why not writers? OK, slightly different: an actor interprets and channels someone else’s work rather than creates it.
Well, one piece of advice i’ve taken is don’t let your creativity be thwarted by what others might think.
