Alright, stepping back a bit...
Samsaric existence is founded on sankhata-dhammas. If ""Dharmas are without blame", this means that the sum of samsaric existence is without blame either since all the dhammas that constitute it are "without blame".
Yet, there is something called "blame", and experience of "blaming" or being "blamed"... and that "blame" does not fall outside the dominion of samsaric existence.
So then, what is it if it's not a dhamma?
