I recently took a belief-o-matic test to see which religion I would be most campatible with. Reform Judaism was the only one that scored 100% compatibility. My birth religion, Roman Catholicism, came 27 out of 27 possible choices, just ahead of Jehovah’s witnesses.
So I am especially pleased that Judaism does not command you to believe in an afterlife, and that in any event, you are sentenced to a meximum 12 months.
Now, If I get a smart Jewish lawyer to defend me, do you suppose I could get that 12 months cut down to a suspended sentence? 
Just joking, folks!
But seriously, it occurs to me that the jEWISH temporary hell after which you are eligible for reward for the good you have done is very similar to the doctrine of Purgatory, which the Catholics believe in but not the Protestants.
Protestants believe that you will either be damned or saved for all eternity.
The Protestant view is based on the idea that God takes everything into account and decides UP OR DOWN.
Except that some Protestants believe in predestination, namely, that it has nothing to do with your works. They believe you are justified by Faith alone. Doing good and avoiding evil is just a consequence of Faith, in their view.
Now, the Protestant view may sound harsh, but the Catholic view is that you will go to Hell if you die wih an unconfessed mortal sin (which could include masturbation) on your soul.
So theoretically, according to Catholic theology, you could spend your entire life feeding the poor, helping others, discover a cure for cancer and bring world peace. But if one day you jerk off and then get hit by a truck 5 minutes later, you will burn in Hell for all eternity.
Of course, this doctrine ensures that believers stay close to the Catholic Church and its sacraments.
