mercy killing causes no harm to anyone. in fact, it provides a relief to the realtives of the victims as they undergo immense agony, seeing a dear one suffering. Euthanasia is an act of professional support to the terminally ill patient and hence canot be held as a cruel act on the part of the person who commints it.
On the other hand, there is a deep rooted belief that life is a god given gift and it is presumptious on the part of a human being to end it. As for taking it away from another human being, howsoever merciful the motive, it is regarded as playing god. If the patient is terminally ill or in a coma, without having expressed any idea on the subject, who is to decide on terminating the persons life? The possibily of greedy and unscrupuluos relatives colluding with an equally unscrupuluos doctor to kill a patient, is a real danger. Morever, though it is an individual decisiom, it cannot be ignored as a major social problem as it opens up a chapter of suffering for the realtives of the patient.
Any law, therefore, on euthanasia should have safeguards to preclude any possiblity of exploiting the situation by unscrupulous elements.
