I say sentence them to death but don’t tell them when the execution will occur. Even better than that: set the stage for the execution every single day, and then most days don’t throw the switch, take the black hood off them, and march them back to their cells. Do it all again tomorrow and every day. Even better than that: make the method of execution especially brutal, like being slowly lowered feet first into boiling oil.

By week 2 they will be begging for death.

By week 3 they will be dead from cardiac arrest.
