The Darkness In Your Mind D.I.Y.M.

The darkness in your mind is a novel about a killer named Harold who meets his inevitable demise and says that if he had a second chance at life he "might" not be such a bad guy he is then reincarnated into a fantasy world without the memories of his past life and gains dark powers that are extremely strong, yet despite gaining these obviously evil powers that could be used in so many wrong ways, he stays true to his word from his past life, in his own ways.
