Mercy Killing-should it be authorised?

In my opinion I feel that mercy killing should be authorised, but it should only be used as a last resort if the individual is under too much pain and would be better off if he or she was put to rest. However, the decision lies in the individual's loved ones' hands. They should have a better understanding if the individual wants to be put down. This situation is evident from a recent case of mercy killing. A 76 year-old woman was put to rest after she has been brain dead for a year. Her children requested the hospital caring for her to remove a life support system from her and let her rest in peace as she has no chance of recovery and would maybe wish to be put down to stop all of her suffering once and for all. Authorities said that the human life is sublime and must be treated with utmost care in any circumstances. Only when a patient has no chance of recovery and medical treatment is limited to maintaining his or her brain dead state. The hospital has thus carried the case to the Supreme Court to verify if this mercy kill is appropriate. In conclusion, if the patient is really incurable and under too much pain or suffering, I think that it would be better off if he or she were put to rest.
