helen,
Hi.
Tough one. You mention a soul retrieval. If it helped earlier then perhaps again? Not all soul fragments may be returned in one retrieval especially if the 'trauma' was significant. And, as you seem to be suggesting, live and let live can be a functional approach. I also might not entirely discount 'an eye for an eye' in some situations (but this is not, I feel where you are looking).
Maybe it is time to put that rug under which stuff was swept in the dust bin, so to speak, clean the floor, have a wee dram, and go on.
Cheers,
RC
