What's the role of "blameless" in the Dhamma?

The word "blameless" is often used in suttas: https://www.google.com/search?q=blameless%20site%3Aaccesstoinsight.org [AN 4.62](https://www.accesstoinsight.org/tipitaka/an/an04/an04.062.than.html) suggests it's highly good: > Seeing clearly — the wise one — > he knows both sides: > that these are not worth one sixteenth-sixteenth > of the bliss of blamelessness. - Is there doctrine about it, or do people just already know and agree on what it means? - Is it given as an ideal for monks and for lay-people? - What is its opposite -- i.e. "blame" -- who does the blaming? - Is it to do with self-reproach? Or with blaming other people, ...? - Is it identical to "absence of remorse", which [AN 11.1](https://www.accesstoinsight.org/tipitaka/an/an11/an11.001.than.html) explains is the purpose of skillful virtue? - What about "irresponsible" -- behaving badly, not accepting blame, even blaming others instead? - Does someone know correctly whether and when their life is blameless, or might they be self-deluded? - What about the Lokavipatti Sutta [AN 8.6](https://www.accesstoinsight.org/tipitaka/an/an08/an08.006.than.html) -- does that say that "desirable things" (e.g. "blamelessness" in this context) shouldn't charm the mind, and its opposite shouldn't be resisted? Is blame and blamelessness just another of the worldly winds?
