Euthanasia

Euthanasia literally means "easy death", but it is actually the killing or letting die of a person deemed too ill, injured, old, or disabled to live a pleasurable life. In the society where the expired are thrown out, euthanasia is performed in order to maintain proper "social health."
==Ethics: is it morally right?==
In most civilized societies and even in developing societies, life is regarded as a valuable quality of a being, making him/her worthy of dignity and protection. For this reason, murder is a crime and killing is acceptable only in very limited circumstances.
