DaasYochid,
I disagree with you on the semantics. Someone who doesnt have a severe disorder is not a �choleh� (shoteh would probably have been the more halachically accurate term) but is in fact a baal aveirah. There�s really no in between.
Point taken, but with the caveat that I would then argue that there are different “degrees” of baal aveirah, and one’s nisayonos plays a role in that.
