“Why is it that it is somehow evil to allow someone to curtail their own suffering and die, but it is fine and dandy to keep people alive against their own free will, no matter how much torture they are being put through?”
Read the thread. In the hands of government, “allowing” quickly becomes “bureaucrats imposing.”
In addition, of course, suicide is a mortal sin.
I read the article and it admits to using a slippery slope argument. Translated, that means it is a weak argument.
The mortal sin aspect would depend on your religion. I am Jewish, and in Judaism, it is a murky matter, at best.
Perhaps it should be up to the individual and their particular beliefs.
