Is Hell or Prison the best cure for immorality?

[Rabb Allah]

Morality is different to justice, morality is subjective and is different from person to person and from society to society, my wife can go out unescorted by a male here but in some parts of the world that would get her arrested by the religious police for immorality.

I am referring to the application of divine justice and it's effects on morality.

All religions as of now have at least some concept of divine punishment for immorality and it seems to me that this has worked to a varying degree all until mankind stopped believing in hell. Although there are the religious wars and what not. But on the small scale level it seems to have done something.

Is a just hell better than a just prison?

When was this golden age in which a universal belief in hell prevented anyone from doing bad things?

Who ever said there was a golden age or that it worked out? Although I will add that the belief in hell kept an awful lot of Christians in line and made nuns deform themselves to prevent being rape bait. Hell has its psychological applications
