Question: Why are some consequences (such as punishments, penalties) in Torah Law permanent, with no appeal or way to alleviate? I am looking for a general covering this topic ideally using an answer that case studies the point that once a wife has cheated on her husband they are no longer allowed to remain married ever again.
Background: What is the concept of forgiveness as it relates to relationships between people in Judaism? Are there forgiven and unforgivable sins? Forgiveness means forgetting any hurt or feeling of revenge, does it depend on whether the person regrets it or does it not depend on it? Does forgiving mean having previous relationships again?
Observing the Torah this of forgiveness is a very strange concept for me but it seems to exist in the Jewish core, the common people and here I include myself see the Torah as a set of laws and punishments, with no scope for the law to punish an interval of repentance or forgiveness, even the concept of teshuvah that I've done here still has many doubts. It is said that God forgives everything, even the most vile sinner but apparently men have sins that cannot be forgiven such as adultery on the part of the wife since adultery on the part of the husband towards his wife is not recognized, he has to separate from her.
So how is this structured in Judaism? I want to hear the whole story if that segmentation exists.
There are similar questions already asked on this site that I have already seen but not with doubts like mine, so do your best to offer an adequate answer to each of the points in doubt, you don't need to answer all of them, you can answer all or just one
