Physician-******** suicide should always be an option for prisoners sentenced to life (or death, in courts that still carry out the death penalty).
1. It saves taxpayer funds, which makes the pro-death penalty advocates happy...
2. ...without the risk of executing an innocent man, which makes anti-death penalty advocates happy.
3. Guards and other prison staff have less prisoners to manage, and thus safer working conditions.
4. Since guards have less prisoners to manage, and more time and energy to invest in activities that keep other prisoners better occupied from attacking each other, those inmates who will be released someday have safer living conditions and become less likely to recidivate or return to prison after their release. (When about 1 out of 2 ex-convicts recidivates within 3 years of release, this becomes crucial to better prison management.)
5. Prisoners who'd choose to have a physician help them commit suicide, would otherwise try to hang or stab themselves. This means that prison guards don't have to cut down prisoners' hanging bodies (which takes a toll on their psyche)...
6. ...and medical personnel have less patients to treat, and more time and energy to invest in treating their other patients.
