Euthanasia [plea for death]

Euthanasia  "an easy or happy death," from eu-  "good" + thanatos  "death." Sense of "legally sanctioned mercy killing" is first recorded in English 1869. It is also known as "mercy killing". The act of putting to death painlessly or allowing to die, as by withholding extreme Medical measures, a person or animal suffering from an incurable, especially a painful, disease or condition.
Should it be allowed:
yes on very first sight, everyone will say "yes". that is like "love at first sight". so thinking spiritually or morally that special one should be allowed to die. but when we start to use our mind we try to figure out many issues, so we get little confused and say do not permit any person to die, because it may become a trend. but in all circumstances it should be allowed. Life and death is not legal issues, its social issue only. social issues can be legal but not all always. so there is need of thinking about life and death, what that means socially.
Life: In our society a person is alive if it is active in society (in any good or bad manner). Society knows only them, who frame next version of society. If a person is living alone at unknown place, their life has no significance for society.
Death: A person useless is treated as  dead.

We use the term LOVE and SYMPATHY. these two words makes society inter-relationship. so if a person is sought for sympathy, there is no need of him/her. Society has no meaning for that person so if that person want to die, due to worst circumstances. It should be allowed, because death is sure.
Let's take an example:
if an animal get injured seriously and it is about to die after few hours, we kill that immediately.
Killing an animal for meat is purposeful and not crime, and euthanasia is not purposeful.
"bakra halal" (a musilm ritual ) in which goat neck is cut very slowly with "mantras". Each knows that after few minutes that will die surely but he suffer that few minutes in very deep pain. same is in euthanasia. here also person death is sure only that time is too long and pain is also unbearable, then just help him/her to reduce that time, allow that person to die. why making it ritual like scene. it is not a ritual. Here need to behave like a human, not need to be show that you are going to interfere in GOD rights, don't try to be a wise person.

"Life itself finds its way, it has everything what that needed, it provides you opportunity to modify yourself, if you don't predict it correctly, Life itself force the change in its own way. so here behave like a wise person and act accordingly. don't show off there, where you need not to be.
