Good and evil are concepts of a young species -- your species. You did not always believe this way. Before this being you call the Christ began his walk on your plane, there were my people -- the Vikings and Scandanavians. So many others. The ones you call the "pagans" and the "heathan". They understood the duality of nature, the cosmic balance and the necessity of both dark and light to the great Is.
I am not Good or Evil. I am not Dark or Light. I am properly called Grey. I stand with one foot in both and my existence is to create the balance for either. My chaos serves neither and both. I fulfill the need to destroy the old so that the new can replace it, so that soul growth can go on.
I am. Nothing more.
I am the REAL Loki.
