>More death-row inmates have been volunteering for their executions: Between 1993 and 2002, 75 volunteered for death, compared to the 22 consensual executions between 1977 and 1992. (Gary Gilmore, the first prisoner put to death after the Supreme Court reinstituted capital punishment in 1976, "volunteered" for his execution in 1977 because he did not want to live the rest of his life on death row.)
It's probably more an indictment of the torture they go through on death row than it is a signal that they all secretly have a death wish.
If they were given the option to send all the resources that get spent on them rotting in prison to a cause of their choosing - many of them would quickly choose a humane death.
The ones that wouldn't, only care about themselves and should be treated accordingly.
