I am not sure what the motives have to do with it if people are being totally honest and their motives are non-harmful. What if there was a fire and you put it out. The highest motive would probably be altruism. But perhaps you wanted to be on TV. Perhaps you wanted to get an award. Perhaps you wanted to impress a cute guy. Perhaps you wanted to get points for purgatory. It probably would not matter to the person you pulled out of a burning house what your motives are.
