Dang, I really thought he was going to choose the healing dragon thing to save all the villagers who were hurt
I was originally thinking that the after choosing the healing evolution, he could have saved the dude instead of killing him for a power up and then just take the egg and run away with it so the dragon goes away too.
The healing evolution was also known to be the hero's familiar too so it would have been a lot easier for him to become friends with the humans
