To give credit to early believers and the idea of faith understood as such,
the harshness of a Jehovah representing the earliest drafts of the idea, when
there were tribal disputes and Mosaic law punishment, seems to have already been
taken into account by Christians, who ended it and didn't ask for their religion
to be made law of the land with punishments, and the Jews, with capital punish-
ment being made rhetorical in the 1st two centuries AD by the earliest rabbini-
cal Jews.
"Forty years before the destruction of the Temple in Jerusalem in 70 CE, i.e.
in 30 CE, the Sanhedrin effectively abolished capital punishment, making it a
hypothetical upper limit on the severity of punishment, fitting in finality for
God alone to use, not fallible humans."

Some later developments (Theodosius I in 380 AD, Muhammad, etc.) were 'centric
political regressions.
