The questions concerning the matter of euthanasia are considered to be burning and significant during a long period of time. It is very hard to decide whether to support or be completely against euthanasia, both voluntary and non-voluntary. Advances, which are inherent to modern medical technologies, innovations, which make treatment safer, and painless, and choices, which patients get during their treatments – all this raises people chances to continue living, get proper treatment, and not suffer too much. However, when we talk about the right to live or die, numerous doubts, uncertainty, and even fear take place. Lots of diseases cannot be treated, and patients often ask to end their lives by means of some drugs or medicines and deprive them from terrible suffering. Doctors can agree to help patients end their lives and use such practice as euthanasia, but still, lots of ethical, religious, and personal disagreements may become another problem for doctors, patients, and patients’ families. Jack Kevorkian and Karen Ann Quinlan are the names, which influence the development of euthanasia in the United States. The investigations around these names, evaluation of ethical and religious perspectives can help to clear us whether people still have the right to live or die, whether euthanasia is just another type of homicide, and who should be responsible for this very practice. Methodology The study under consideration originates from a burning need to decide whether modern medical services provide patients with the right to live or die and whether patients themselves make the decision to continue living or die. In 1976, the first Natural Death Act was approved and became one of the most controversial laws (Miller, 2003). Of course, not each state was eager to adopt the same law, however, within two decades, all other states proclaimed the similar laws, which could protect the patient’s right to die. At the end of the 1970s, the case of Karen Ann Quinlan also became a significant factor for numerous ethical debates; however, it served as another important point that promoted legal protection of euthanasia (Naden, 2007). Finally, the questions of euthanasia were raised once again at the beginning of 1990, when Dr. Jack Kevorkian assisted more than 100 suicides and taped all the procedures. His actions, discontent of numerous religious people, and disparity of many ethical issues promoted the creation of the Oregon Death with Dignity Act with a number of safeguard issues (Ars & Montero, 2004). The investigation of case of Karen Ann Quinlan and a deep analysis of Dr. Kevorkian’s actions turn out to be a good approach to decide whether the right to live or die is still available to people, or whether it is necessary to pay more attention to doctors’ activities and the circumstances under which the decision to unplug feeding tubes and respirator is made. Discussion Essence of Euthanasia and Its Consequences Lots of sources identify euthanasia as a practice of easy death, mercy killing, or just the right to die (Naden, 2007). There are actually several types of euthanasia: voluntary, also known as active, when a patient just asks to kill him/her and stop his/her sufferings; involuntary, when a person cannot express own wishes because of coma, immaturity, or other mental problems; and finally, passive, when all the necessary supportive devices are withdrawn
