I don't think he should be allowed to die by hanging. String him from a thin rope so that it just breaks under the weight of his body. He falls onto the floor and dislocates a couple of upper spinal discs. Then let it 'ripen' for a week till it suffers from inflamation, edema (fluid accumulation), swelling, excruciating pain and he is unable to turn his head. Now have a prison guard grab him by the neck and move him around a little. Repeat 'botched hanging' after a month. And yeah, no pillows. He sleeps in his cell on a hard stone floor.

I don't believe he should be tortured to death, either. Torturing a sick animal just because it's a sick animal is inhumane. Hang, shoot, or inject, but get it over with. Then wash hands and on with life. Just because he was a sick puppy doesn't mean the rest of us have to turn into one, too.
That sounds like the football coaching methodology of Saddam's sons.
