My uncle died a slow, horrible, and painful death. He had oral cancer. The doctors removed most of his of his lower jaw, part of his tongue, and areas inside his mouth. He couldn't talk. He couldn't eat except through a feeding tube. He had a trache that came out of a hole in his neck so he could breathe. The trache was always getting clogged up with drainage and blood, breathing was difficult. The cancer spread and began deteriorating the bone in his face. His head became swollen and knotty. Even with strong pain meds, he was in a world of agony. And if all that wasn't enough the swelling spread to both eyes and he went blind. His eyes was being pushed out of their sockets by the cancer. He couldn't talk or see, he was trapped inside himself, suffering more than I ever knew was possible. Eventually he became immobile and couldn't move at all. He passed away last year, eight months after the surgery, and he suffered everyday.
I would not wish that kind of suffering on anyone. Not even America's worse enemies or the most vile people ever. If you ever witnessed suffering, you couldn't wish it on anyone either. No matter how tough you may think you are.
