Reincarnation of the Overpowered Young Lord's Journey

He was once revered as a great hero, but was betrayed by the people he guided and helped back in the dark times. However, Karma seems to side with him, as the very people who betrayed him disappeared at the same time, yes they all died at the same time, together with the planet that turned its back to him. The hero became a mindlessly destroyed, bringing forth chaos and destruction upon the sinner that destroyed his world and people. From worlds, galaxies to civilizations he had journeyed all around the infinite universe to enact his revenge slaughtering everything in sight mindlessly still being controlled by the people who betrayed him that had long since perished.
