I do agree it does take the mystery out of it. I have had the same thoughts. But it's so much fun getting the pictures I can't resist putting out a few cameras. You still have the mystery of not knowing exactly what you're going to get with the camera. Like the occasional bear, cougar, or bobcat when all I'm expecting is deer or elk. This year I have cameras out in two locations where I won't even be hunting, at least not this year.
I would suggest going without bait, if that will make you feel better about it. You won't get as many pictures but at least they will be more natural.
