This is just wrong, very wrong.
Yes, the law may forbid other people to actively assist such endeavors because of the serious possibility of abusing. But, ending one’s own life could be a liberation in same cases. Forcing someone to endure ceaseless, utter pain and hopelessness is tantamount torturing and abusing, and in my view is absolutely horrific and despicable in every way.
Human dignity is inviolable. This includes ending one’s own life with dignity.
