I agree with you, I hope you aren’t misunderstanding me. I don’t believe a novel can compel you to sin unless you’re predisposed in some way to a particular vice. I know we’re talking about murder novels but I’m speaking more in general. I doubt there are many people who will be tempted to kill someone after watching an episode of CSI, afterall. The only other thing that one has to watch out for when reading or watching television is if the reading is swaying you in a direction contradictory to church teachings, but again, this is rare, and is usually only a problem for people who are spiritually weak in the first place.
So really, most fiction is perfectly safe for most people. There’s no sin in enjoying secular fiction, even when it depicts horrible sin or questionable morality, and I never said there was. My favorite series right now is about a fictional world war, involving genocide, mass execution, mind control, and a LOT of using sin as means to a just end, things very contradictory to church teachings. But viewing and enjoying something isn’t a sin, even when it’s depicting sin. And most people won’t find most fiction even an OCCASION of sin, and those who do, it’s usually along the lines of sexually provocative content, not corpses or war
I’m just regurgiating church stance, my friend, not necessarily my own opinion. My own opinion is pretty much, if it ain’t porn, go for it. You know what you can and can’t handle.
