supererogation
(en)
(noun) the act of performing more than is required by duty, obligation, or need
It was as if by the mere act of betraying her husband, she had adequately bested him; it was supererogatory for her to gloat, and, if she gloated at all, it was over her fine restraint in not-gloating, over the integrity of her moral sense
