on second thought my Nidah “rayah” might not be one at all.
Its very possible that although we would rather he be with nidah than goya (an assertian I am being strictly based on sevara I would love any sources on this topic) , He is doing a worse aveira., but we would rather he do worse aveira for a greater good.
Although we don’t say חטא כדי שיזכה חברך, ( shabbos 4a) in the tzad that we did say that. Do we say the person doing the aveira still has an aveira, he is worse off for having done it , he will get an onesh/need kaparah. But do the aveira ie get the onesh, ie do the worse act, to benefit your friend.
Or no, in that tzad, it wouldnt be the worse act, NOT doing the aveira would be worse maybe he’d even get get punished for not doing the aveira . There has to be some discussion on this, I will go hunting over shabbos bl”n. Though I’m not certain it relates to our topic
