I would prefer the person who wishes to die to find their own way. I can't see why taking your own life can't be pain-free.
I wouldn't like to be in any sort of relationship with anyone who was allowed to euthanase somebody. I don't believe there is any way they could continue to have the same regard for life once they have started dishing out medicines which take the lives of others
So you wish them to die alone and in pain? how inhumane.
Suicide is rarely pain free due to the fact you do it however, there is no getting right combo of drugs to do it peacefully
Jumping in front or off of something leaves other victims, the ones who find you and you wont always succeed.
Slashing ones wrists or other mass bleed areas is a traumatic find for anyone.
I actually think those who wish to see people suffer cos of their own feelies have no regard for life. Life isnt just being alive, its about having a quality of life you feel good in, you feel wanted in, you feel needed in.
