In the Eternally Silent Cemetery, I Can See the Mental Thoughts of All Living Beings

Is There Any Novel in Which the Main Character Is in a High-Spirited State of Mind and Is Not Violent?

I want to read a book similar to "The Immortal Cultivator vs. Super Power". After reading novels, animations and movies for so long, the basic protagonists are all from good to evil, with high abilities but no matching state of mind. Is there a protagonist who goes from evil to good and has a high state of mind?
