There is nothing like good or evil in God's creation. Everything odd, bad, evil is just our imagination. There is no hand of God in all this. If we believe there is God. If he is the Almighty, All powerful, formless, omnipotent, omniscient and if He is peace, love, then why people think of an equally opposite evil power. Not all desires are fulfilled, not all visualizations get manifested. If we talk about karma, then there is no I. Karma is not a simple thing, it is the main cause of our recycling, continuous, births & deaths and all sufferings. If our karmas are not dedicated & targeted towards one union with the all pervasive, allmighty God then our all karmas are in vain.
