Funny thing- In the past, when I wasn't aware of the term 'Euthanasia', I used to wonder why mercy killing is called 'Youth in Asia'. Funnier thing- I have observed that this phenomenon is most common among 'youth in Asia', so in a way, I was never really wrong. On a more serious note, should Euthanasia or mercy-killing be legalised?
On medical terms, euthanasia has been defined as the deliberate intervention undertaken with the express intention of ending a life, to relieve intractable suffering. So my verdict is that- only voluntary euthanasia should be decriminalised ie. only those individuals who themselves want to end their life should have the right to carry out such abnegation. E.g. A paralysed man who has lost all hopes of moving any part of his body except his head or a cancer patient with malignant carcinoma which is nowhere near recovery or an AIDs patient who has been condemned by the society and both pains-physical and mental, is unbearable, would rather prefer to die than to live.
Currently Euthanasia is considered as criminal homicide. It may be so for cases of non-voluntary euthanasia, namely child euthanasia or honour killing when two individuals in love are killed by their own family members if they are of different castes or same gotra of the same sub-caste. But for cases like those mentioned above, most certainly not!!
