The word akin to that also occurs in DL X.137:
137] He further disagrees with the Cyrenaics in that they hold that pains of body are worse than mental pains ; at all events evil-doers (ἁμαρτάνοντας hamartanontas) are made to suffer bodily punishment ; whereas Epicurus holds the pains of the mind to be the worse ; at any rate the flesh endures the storms of the present alone, the mind those of the past and future as well as the present. In this way also he holds mental pleasures to be greater than those of the body.
ἁμαρτάνοντας
