We can't be too much judgemental for an issue that has many challenging subjectivity related to it. The discussion will have both the side, yes as well as no also the situation of the, environment, laws of the state and most important thing is ethical considerations has to kept on table before making any statement.
Ethically we can't calculate the value or contribution of a person to maintain his life saving expenditure or the cost benifit ratio. If we equate human life equally than we cannot make this legal. That means the XYZ, has equal right to live like the Staphen Halking did.

Practically the ethical issues can't work, we have to decide on the basis of contribution of the terminally ill patient, will the contributions of XYZ be equal to the life saving support he is put on. A hospitalized person needs the aminities equal to 100 poor, illiterate and hungry people. Isn't there ethical considerations human. If it is about human, isn't than an Indian, African or Afghanistani human?
Being in medical profession, as a doctor I have seen the real struggle of people in a hospital. If you check the real situation visit an neurological ward in Indian hospital and decide Euthanasia.
I think if the patient has a terminally ill condition and is on active machine support, he should be provided the Euthanasia support, that means we must draw away his life saving support. The "other ways" must not come to effect. The other ways I mean to say right to die, a normal person must not be allowed to make a decision of his life and the normal I mean a physically as well as physiologically.
I don't think right to die is a rational comment. I don't think it is moral too. If you are human you have to cope with situations you are put by nature. You need to adopt the situation.
Some people think of dignity, when you end your life by self satisfaction, where do the dignity lie.
I believe too in Euthanasia, only in cases of terminally ill diseases. The question may arise who will define the condition of terminally illness. If one is terminally ill today and we remove his life support tomarrow the cure is found. Isn't that injustice to him or her. For the collective good we may be proven wrong sometimes but these are exceptional situations and they will remain there.
In my conclusion I am in favor of Euthanasia but only in terminally ill patients and not with right to death..
