answer

During the soul-searching I did, I came up with a classification into two types of things: A. Sins that stem from petty things (laziness, and other desires of that kind). on. Sins that I supposedly ‘stand behind’, but not completely. To ‘disrespect’ (meaning to come to the conclusion that they are incorrect and not take them seriously) all sorts of opinions of rabbis and the like.
The problem is that on the one hand something tells me that it’s not right, on the other hand I think so, so how is it even appropriate to repent or regret something like that?
For the sake of the question, I was thinking of a secular person (who truly thinks so), who doesn’t seem to be the type to repent for his apostasy, right?
My question is actually whether the concept of repentance applies to things other than lust and self-renunciation (weakness of will)?
I hope I presented the problem well. Thank you very much.
