The goal of euthanasia is death of a human being under the excuse of alleviating pain while dying, and it is often referred as mercy killing. This paper aims to describe the problematic behind the concept of euthanasia, and seeks for the reader to question their stance on this matter. The first chapter analyzes the meaning of the term ‘euthanasia’ as it lists different types so the reader can familiarize themselves with the topic in question. Euthanasia is divided in terms of cause as active or passive, in terms of consent as voluntary or involuntary, and in regards to intention as direct or indirect. The second chapter observes euthanasia throughout history. Various euthanasia evaluation perspectives are presented, as well as specific practices for individual historic periods. The first documented man’s reflection on euthanasia date back to Greco-Roman world few centuries B.C. The first publicly featured supporters of euthanasia as we know today, who demanded the right to death, appeared in the 19th century. Euthanasia reached its peak during the Second World War. The third chapter dissects views on modern era euthanasia. Opinions and views of its supporters are listed. Their ideas rely on the belief that euthanasia means compassion toward the ones suffering. Some euthanasia advocates openly talk about high costs of medical care for those seriously ill which could be evaded with euthanasia. Some euthanasia supporters consider certain groups of people as useless eaters that should be killed in the name of expense reduction. Furthermore, some state that human is the last instance and should therefore have a choice in the decision. This chapter also features the opinions of those who oppose euthanasia. Humans’ dignity is reassessed under different views; the correct comprehension of health, pain and suffering is reconsidered; the background of people who filed requests for euthanasia is observed as well as various difficulties and irregularities that would arise in the case of legalizing euthanasia. Thinkings of the Catholic Church on the issue of euthanasia are also introduced and several church documents are presented on the topic. The fourth chapter talks about dysthanasia, which implies artificially prolonging the life of a terminally ill person using different tools and equipment in order to maximally postpone the death of the patient. Dysthanasia aims to achieve this goal even when there is no hope for the patient to get better. This chapter questions the integrity of this procedure and offers the stance of Catholic Church 42 as the correct one. The conclusion asserts the Catholic attitude as the only competent and accurate one in respects to euthanasia.
