Honestly I thought about it for a moment but I don't personally have a problem with it, because you stated clearly it's fiction, if you were claiming it as fact that would be an entirely different issue. Go with your heart, let the spirit lead and if that's what you are lead to write then go with that, if you feel convicted though that's an entirely different matter, but I mean convicted inwardly because though peoples opinions matter to an extent ultimately you have to write what's on your heart, and you do so beautifully...
