Another question on Luke 23:34

Somewhere I once came across another angle on "aphes autois" in this verse: thataphes means "permit" and that the prayer is intended to avert immediate judgmenton the ignorant soldiers, not to secure their forgiveness.  "Permit" is no
doubt within the semantic range of aphiEmi and there is perhaps a problem with
ignorance as a basis of forgiveness, though not as a basis of averting
immediate judgment.  Any comments?
