I'm for the death penalty. Murder, tax evasion, arson, grand theft and such are all good reasons.
Public beating and labor camps for other criminals of lesser crimes.
Death by the ever efficient guillotine. Quick, painless, cheap. People have survived the electric chair and other execution methods, I have yet to hear of a guillotine survivor.
Kill one warn a hundred. Crime prevention.
Even if it were me who were guilty of the mentioned crimes, justice still needs to be carried out. Come and kill me French Revolution style if I become guilty of any aforementioned crimes.
For those criminals who want to die, kill them, of course. Why should any of their wants or desires affect the course of justice, which should be impartial?
