That group will be composed of the insane/irrational, those who value power at extremes, those who value improving the world over their own lives, and those who have lived long enough that they're ready to move on. The last two categories are great candidates for empowerment, but one is rare and grows rarer, and the other doesn't show up for upwards of centuries.

Unless you mean they only face death for the duration that they are in power, as an enforcement of term limits. I don't think that is materially different from other enforcement of term limits- if a dictator is able to compromise the military, they can probably also compromise whoever has the power to stop their impending death.
