We stop feeling pain after death due to our neurons going offline after the execution is done. Today's forms of executions are MUCH LESS painful than the classical counterparts. Injecting chemicals for cardiac arrest, especially after chemicals to put you into sleep, is much less painful than firing squad and guillotine.
Why do we fear death? Hell? Pain after death? Not being able to reunite with your family? Well, life imprisonment is worse.
Death:
- There is no hell proven
- Modern execution methods are less painful
- You aren't meeting with your family.
Life Imprisonment:
- Living there is akin to hell as physical limitations are painful on its own
- Constantly suffering and painful due to lack of space
- You aren't meeting with your family anyways, probably.
We are too scared of death. Death is less painful than suffering the every second you are existing in a painful place. If I ever get myself in a situation where I have committed a crime harsh enough to guarantee life imprisonment or death(which hopefully I won't), I will choose the latter.
As for being bailed out, if they have to be bailed out after a few years, they should never even get life imprisonment anyways. Genuine life imprisonment is literally hopeless for you and an experience worse than death.
