Atonement? Or Retribution?

On This Day In History
1973: The Yom Kippur War brings the United States and the U.S.S.R. to the brink of conflict

Quote Of The Day
"Until the Yom Kippur War, in 1973, until then Israel didn't have a chance but to fight for her life. We were attacked five times, outgunned, outnumbered, on a small piece of land, and our main challenge was to remain alive."
(Shimon Peres)

On Erev Yom Kippur, the day before Yom Kippur, or Day of Atonement in English, Jewish people seek atonement for sins they have committed during the year. If they are truly repentent and have made a sincere effort to atone for their sins, whether or not forgiveness is forthcoming from the wronged party, then, on Yom Kippur, Yahweh will wipe their sins clean with His mercy in line with His transition from a jealous god when He killed the Israelites for creating the golden calf, to a god of mercy when Moses came down from Mount Sinai with the second set of the Ten Commandments on Yom Kippur. Yahweh seals His judgement on the day of Yom Kippur.

I'm not anticipating a great deal of atonement or forgiveness on Thursday, and I think Jahweh will find His quality of mercy severely strained.

"You won't know my name,
Or my forgiveness.
Mercy's overrated."
No Mercy

When does mercy become complicity in the progression of Evil?
