From our own modern society, a 16-year old died... He will be reincarnated into something that would be considered greatly evil. But is he really evil?

After, his tragic death he was reincarnated into the egg of a dragon, a creature known as a rare legend across the lands. A dangerous monster that can devastate any continent on its own. A monstrous creature that is feared by mighty magicians that are capable of angering the gods without worry, even the demon king doesn't dare to anger a dragon. Dragons used to fly across the sky on an everyday basis until a large calamity had struck. A disease targeting dragons of all species ended their lives in moments. With low birth rates as is only a few dragon families live on, Nine-Teen true dragons live on in existence in this massive world (Take earth and multiply it by say idk 20x) Most dragons are seen as evil calamities because of the destruction they cause from just a flap of their wings but our young hero wishes to change the way they think.
