Justice is revenge dressed in a nice suit!
I do not understand the mentality of someone who advocates life in prison over execution of a criminal. To sentence a person to loss of freedom, to the possibility of being beaten on a regular basis and to the possibility of being raped on a regular basis, is barbaric. To wish to continue to torture a person for life, because that is what it is, is indeed a barbaric mentality. That is cruel punishment. Execution is quick, permanent and solves the problem of the offender ever offending either inside prison or out of it, again.
If I was sentenced for an horrific crime I committed, then I would demand the death penalty. I would rather die a quick death than suffer in prison for the rest of my life. I don't understand why anyone would seek to hold on to life in that situation.
"God is the name by which I designate all things which cross my path violently and recklessly, all things which alter my plans and intentions, and change the course of my life, for better or for worse."
