This dissertation has multiple goals. First to analyze self-destructive behavior and its relations to ethics. Secondly to evaluate four different ethical perspectives regarding self-destructiveness from a certain position of human nature. The third goal is to construct a position that deals with self-destructive behavior in a way that is improved and well-managed compared to the four ethical perspectives analyzed earlier. The first goal is met by comparing and evaluating different theories concerning self-destructive behavior and discussing the ethical implications surrounding them. Self-destructive behavior is seen as a way of communicating, which puts a moral pressure on both the self-destructive person and the society around her. The four ethical perspectives represented by Robert Nozick and Thomas Szasz, two neoliberals, James B Nelson, a body theologian inspired by Paul Tillich, Gail Weiss, a body feminist and Mary Timothy Prokes, a catholic body theologian, are hence met by the problem of self-destruct, analyzed and critically evaluated. In the final chapter the author constructs an improved ethical perspective concerned with self-destructiveness, based on altruism, responsibility and broad-mindedness.
