Partial answer and full answer..

Hello, Your Honor.
 
When a person wants to repent. But is forced to do a full repentance following a sin. Will his previous sins be forgiven and from now on he will be judged only for his new sins. Or is it because his previous sins also cause the present ones that his answer is no answer at all?
 
And I link this question to the interesting issue of whether or not the Noahide is useful for the Sons of Noah.
Because one of the commentators stated that since the children of Noah are found in only 7 commandments, they have no ability to atone for their sin. Since the 7 commandments are a return and a do not, the past sin ultimately comes into account even if one repents at the moment.
And it means that the answer only helps if you “settle the score” with God – it turns out that your creation was more beneficial than the relationship. Then he brings it up in the commentary that if in truth Noah corrected his words to very positive actions like Naaman, or converted like Nebuzaradan, it is also beneficial for him.
 
But what if a person has committed serious sins and is now weak and exhausted and in great depression? Or is physically ill and even if he repents, he will not be able to be a wise scholar, for example? Or has justified many and while he was a sinner, he wronged many.
And what is the scope of a person who was mentally or as a result of environmental circumstances, the boundaries of sin – as a baby who grew up among the Gentiles, for example. And converted to Christianity and only in adulthood discovered the truths of Judaism – and now he has repented but does not know how to learn the halakhic concepts. Or even the Hebrew language. And it is possible that the ways of learning the belief in uniqueness have already gone wrong and as a result of his past he can even now reach lost mental images – such as belief in God as having an image and a picture. Will his sins be erased for him even though he has come to observe the Torah or are his sins included with his new sins?
And what is considered a person who has sinned due to mental reasons, such as a woman who was raped, or a child who was physically abused, or because of a damaged personality that has become ill due to the severity of his upbringing in keeping the laws?
And in general, is repentance preferable in every situation? Because if a person recognizes the Sovereign of the worlds, but on his own terms and according to his own feelings, doesn’t repentance in this case only add sin to sin? (Like many who say that they returned in a hurry because they discovered that religion is beautiful and not ugly. And apparently this is not repentance, but a full-throated admission that they are not willing to accept His kingdom if it does not please them).
