Adrien's past and backstory sounds more like a villain's past.
1. Missing mother
2. Neglectful father
3. Isolated for most of his life (homeschool)
4. Unrequited love
5. Powers of destruction and chaos
However, despite everything, he still chosen to be the good guy and save Paris! He could have easily destroyed the city in no time at all. His cataclysm is powerful enough to reduce the planet to ashes. He's a valuable ally, and a deadly enemy. We're lucky he's a good guy. If he turned evil of his own free will (not by an akumatized victim), not even Ladybug and other Miraculous holders could stop him.
