In trying to research the Sufi's outlook on good and evil, I found this segment and was reminded of the work done by Saint Valentine.
There comes a stage in the moral evolution of man when he perceives and understands the moral of beneficence, and he learns to return good for evil. At this stage in his progress he hears a chord that connects and runs through him and through all. He finds himself as in a dome, in which good and evil find re-echoing tones. Evil done to him echoes within him in a desire to do evil in return; and good done to him echoes within him in a desire to return good. Therefore, in order that his own actions may in their turn call out nothing but good, he desires always to do good, and to return both good for good and good for evil.
https://wahiduddin.net/mv2/III/III_II_18.htmSaint Valentine was held prisoner, and showed good will to his captors. At this stage in ones life, I presume you do good not just for the benefit of the other- but a service to a higher ideal, God... Who alone becomes the object of desire, to please and to commune with. In this life or the next. Saint Valentine must have been moved by such a large omnipresence, as was Yogananda and all who seek God earnestly.
