Consider this scenario, your mom is on the death bed battling with a terminal illness, incessantly complaining of both physical and mental pain, then she suddenly requests for your presence then weeps and beg you to take her life, you called the doctor and professional psychologist and they both confirmed she is in her sane mind, suppose then that a Legal Right to die is legal in your country, will you succumb to her request and take her life or do otherwise and watch her struggle with the maladies of pain till she dies?

What would you do?

It's a practice called "mercy killing", doctors and nurses can relate to that.

Besides death is not a bad thing if desired by an individual, how else would the "cycle" be maintained
