What I have to say as others did is how did he get so fat in prison? Do they get to eat as much as they want? And he doesn't do anything so he just gains weight? Something is wrong with this scenario. He rapes and kills two girls - he goes to prison where he eats all the time and obviously doesn't do anything to taxing to wear off the calories. And then we worry about the pain he might be under if the medicine doesn't work right with his other meds? So easy to fix - put him on a diet, an exercise program, give him some real work to do, stop the meds for his headaches long enough before the execution so they will no longer be a problem. (what difference if he has a few headaches before he dies).

Again, HE might feel pain? Not only did those girls feel a lot of physical pain as he raped and killed them but the unending pain he has brought to their families who not only have to live without these girls but the thoughts of how they died has to be terrible.

He certainly did not act humanely - why should he expect humane treatment!
