The larger issue, is do you believe a person has a right to commit suicide? If not, what punishment should the government enact for your decision?
It is not your decision to kill another person who is suffering.
Suicide is against the law in most of the civilized world. The law is gentle when the suicide attempt fails and help is usually given.
You have the ability to make the decision for yourself, but asking others to assist you in carrying out your wishes is another thing. You do not have the right to impose your desire to die on the consciences of others.
I watched my own father die of cancer and held his hand as he went. I know what it means to see a loved one deal with pain and illness. Adding suicide to what is already a tragedy doesn’t help anyone.
