Many of the world’s major and powerful cultures have not only permitted suicide but actually condoned acts of self sacrifice—Ancient Egypt, Classic Rome, China for almost three thousand years, Japan from pre-history into the 20^th century, and Moghul India are but a few examples. Several major religions, including Islam and Hinduism, approve of suicide under certain conditions. On what basis have we the right, then, to say that suicide is wrong?  Using the articles and media from the week, examine instances in which you believe that it is acceptable to kill oneself or to sacrifice oneself and then explain instances in which you think that it is not ethically permissible to do so.  Be sure to include reasons that support your claims.
