Here is a link to an excellent essay by Richard Stith entitled “Making Death Easier Makes Life Harder.” Here is his concluding paragraph:
“Each withdrawal of protection against suicide endangers not only the lives but also the human dignity and support relationships of persons with burdensome infirmities. By contrast, when our law and culture treat suicide as a tragic rather than a benign choice and refuse to facilitate it, those most in need are more likely to receive sympathetic help rather than guilt-inducing blame and resentment. Opponents of the legalization of assisted suicide thus have not only strong pro-life arguments but also telling quality-of-life arguments that they need to bring up whenever any right to suicide is being debated.”
