This is a specific enough topic that I don’t think it’s fair to try and answer it in a general manner. Art affects people… but it doesn’t directly lead to imitation - Doom and Counter Strike didn’t spawn a generation of soldiers. But were a few people considering it and their experiences convinced them the final few steps? Probably.

Either way art is a good thing and people are more stubborn than you’d assume. If someone chooses to do something art didn’t make them do… did it significantly influence them? I’d want to know specifics before commenting further.
