Rosh Hashanah 17: Sinners and... Sinners

Those who sin against God in a variety of ways go down to Gehinnom, and what happens after that (how long and for what degree) depends on the sin. With all the fear that that induces. Plus, a dig by Rava at Mehoza as sinners. Also, and acknowledgement of God's kindness, and His tipping the scales with mercy, when possible. Plus, leaders who inspire fear for the wrong reasons, and their comeuppance. Also, a strange story of R. Huna and R. Pappa, and recovery from near death, and an encounter with the Divine. Plus, series of verses about the righteousness of God, and also His forgiveness. Also, God teaching Moshe how to ask for mercy with the 13 attributes of God, which would surely be impossible but for the fact that God trained us in it. To what extent is judgement reversible? Perhaps it's not as simple as we would hope.
