It’s one thing to commit suicide oneself.
People do it every day.
It’s entirely another thing to want doctors to be able to kill people. Call it “assisted suicide”, “euthanasia”, or “death with dignity” - it’s murder.
Dignity is what a person brings to death, it has NOTHING to do with how they die and even less to do with how they “look” when they die.
Hitler had a party before he died, dressed in his finest uniform and chose the exact manner of his death. I’m sure he “looked dignified” before he died, but he didn’t have a shred of dignity.
Jesus Christ was stripped naked, beaten, mocked and nailed to His Cross. It’s very unlikely that He “looked dignified” to His executioners, yet He died with more dignity than anyone who will ever live.
