The fool has set in his heart that he can get more money through the tiring of his muscle and the starvation of his brain-but he can't.
The issue is not whether there are horrible cases where the penalty seems "right". The real question is whether we will ever design a capital system that reaches only the "right" cases, without dragging in the wrong cases, cases of innocence or cases where death is not proportionate punishment. Slowly, even reluctantly, I have realized the answer to that question is no- we will never get it right.
