Ron and Mich are demonstrating extreme ignorance. Please search this site (google bar at the top right corner of this screen) for the keyword "necromancy" and I'm sure you will see an abundance of information and leads to get your research started.
Death, just as life, is pure until tainted. Either can be light or dark. It all depends on which path you wish to walk down and what your perspective is.
Have you ever heard of a "good death" or even "beautiful death"? Death isn't always feared or resented. In my opinion, it should never be feared. It is a fact of life, it is the end of the cycle of life that begins again in rebirth. Without death, we would not survive. Everything you eat or drink, unless 100% artificial, died and you are living off of that nourishment. It is an amazing cycle that is commonly overlooked.
