No, the person is put to death for his actions, regardless of the reason.
Do you think justice is served by putting someone to death? Who precisely does that help? Does bring anyone back from the dead, onle life for another!
What a wonderful message to send to the masses - 'errr don't kill people . . . . because we'll kill you if you do'
In the first instance capital punishment does more to make murder acceptable then otherwise, if the government can do it with all these millions of people watching then so can Joe the plummer . . . .
If someone who commits murder is to be given the death sentence, then what happens to everybody involved in a court proceeding where someone is wrongfully given the death sentence? Are they then guilty of murder, should they all face death because they lacked the capacity or knowledge to make the right decision? Hey, lets go further, even the death penalty for guilty people could be construed as murder by the courts, pre-meditated decision to end human life. You back this system, so maybe you should be given the death penalty for backing it?
