Different cultures. The monks that live in the mountain, they sometimes have to kill to survive, but they respect the animal they kill by making sure nothing goes to waste.
If you somehow have the nerve to request power from a dragon, you'd better be willing to make a dear trade for it, if you don't want to end up 'extra crispy' or your home to be flooded or trampled. That is what I mean by 'fools who take the power of the dragon', there is always a price to be paid even if the dragon finds favor with you.
