Agreed .
Killing this monster would be a kindness to him.
Put him in solitary confinement for the rest of his life and let his contemplate his paralyzed legs, the humiliating fact that he is powerless to control any aspect of his existence, and miserable quality of life he has created for himself.
Most importantly, killing him to provide for him an honorable, highly publicized martyrs death is obviously what he wants and is trying desperately to achieve.
We should make sure this is denied to him and instead let him face obscurity once the trial publicity dies down. It is better that we allow him to stew in his misery, and self inflicted humiliation to contemplate his powerlessness and personal degradation alone, forgotten and unheralded by the rest of the world.
Once they actually do execute the POS he will become a highly publicized martyr
He just ain't worth the trouble.
Wheel him back to his lonely cell with minimal fanfare, lock the door, throw away the key and let him rot in Military prison under the military justice system which is much harsher than the civilian prison system.
