"Blame" means "blamed, censured or criticized" by the Buddha; similar to being condemned by the Biblical God Yahweh for your sins.
Buddhism is not an escape for ex-Christians from being blamed, judged and terrorized with threats of being sent to hell. MN 130 particularly shows the extreme horrific depictions of hell held to be believed & taught by the Buddha.
Also, there are many suttas where the Buddha appears to accept capital punishment is the inevitable outcome of certain bad kammas, including adultery (which many secular cultures such as in France appear to now hold to be OK, fun and acceptable; such as married men & even married women having mistresses & lovers). For example:
The blood you have shed when, arrested as thieves plundering villages,
you had your heads cut off... when, arrested as highway thieves, you
had your heads cut off... when, arrested as adulterers, you had your
heads cut off: Long has this been greater than the water in the four
Then King Yama says, 'My good man, didn't you see among human beings
kings — catching a thief, a criminal — having him tortured in many
ways: flogging him with whips, beating him with canes, beating him
with clubs; cutting off his hands, cutting off his feet, cut off his
hands & feet; cutting off his ears, cutting off his nose, cutting off
his ears & nose; subjecting him to the 'porridge pot,' the
'polished-shell shave,' the 'Rāhu's mouth,' the 'flaming garland,' the
'blazing hand,' the 'grass-duty (ascetic),' the 'bark-dress
(ascetic),' the 'burning antelope,' the 'meat hooks,' the
'coin-gouging,' the 'lye pickling,' the 'pivot on a stake,' the
'rolled-up bed'; having him splashed with boiling oil, devoured by
dogs, impaled alive on a stake; cutting off his head with a sword?
Instead of legalistically searching for the meaning of words in dictionaries, it is best to read suttas for a contextual explanation:
Of course you are uncertain, Kalamas. Of course you are in doubt.
When there are reasons for doubt, uncertainty is born. So in this
case, Kalamas, don't go by reports, by legends, by traditions, by
scripture, by logical conjecture, by inference, by analogies, by
agreement through pondering views, by probability, or by the thought,
'This contemplative is our teacher.' When you know for yourselves
that, 'These qualities are unskillful; these qualities are
blameworthy; these qualities are criticized by the wise; these
qualities, when adopted & carried out, lead to harm & to suffering' —
then you should abandon them.
Buddha: There are those families that were friends of the bhikkhu Channa, Sariputta, families that were his intimates, families that were blameworthy; but I do not say that to this extent he was blameworthy. Sariputta, when one lays down this body and clings to a new body, then I say one is blameworthy.
