This is a very touchy subject especially in religious views.
So I will put my religious thinking aside.

Though I have very mixed torn feelings,
I also believe in human euthanization, but for only certain circumstances.
Thier has to be no longer a quality of life nor hope
for the person could get better.
IF the person is dying and suffering, why prolong the
suffering more?
My mother suffered from Cancer.
But the last month of her life was horrible for her.
I think it would have been
much kinder to let her go peacefully towards the end.
Instead she was so full of morphine and she died
in a hospital bed.
