Some may argue that mercy killing, or euthanasia, cannot be justified on the ground of ethical concerns. However, I personally believe terminally ill patients should have the right to die when they choose. First, patients with terminal diseases often suffer a great deal from living in a hospital for a prolonged period without any chance of getting cured. For example, terminal cancer patients might have to get through a number of medical procedures not to improve their conditions but just to try to keep their lives longer, which causes them a lot of suffering until they die. Second, the costs of treatment for terminally ill patients are prohibitively high, which can impose a heavy burden on them and their families. It doesn't seem reasonable
