Yom Kippur is about getting beyond all the crappiness we humans have managed to do to one another in the past year and starting again. It's not a free pass. You have to make right what you've made wrong. But, the relationship isn't symmetrical: You don't get to demand justice from those lousy bastards who treated you like dirt. You forgive them. And if you don't, you are now the lousy bastard....
We need leeway to live together. We need openness to build a world we can't predict. We need forgiveness so we can love one another or at least not beat each other to death with tree branches.
