There is nothing wrong with your "nature." But the problem lies in your education. Education cannot change your nature, and your nature is always much greater and more powerful than education.
Your truest core-nature is Love. This means two things: 1) You want to love, and 2) only giving and receiving Love can ever bring you full contentment, satisfaction, or fulfillment.
So, make a personal and private vow in your own heart to begin re-educating yourself with truly positive spirituality, and add to that vow that your ideal and goal is to love yourself and all other creatures.
