Would I see them Live? Not if a convicted child abuser was still part of the band.
Would it make a difference when an album was written? Not directly, but I wouldn't buy anything, whenever it was written, that benefitted a known child abuser.
As for the "debt to society" issue, well, my view may part company with the norm on that.
For most crimes, personally, I accept the "debt paid" rationale. Even, in most circumstances, for murder.
But for the nastier examples of child abuse, and I mean actual paedophilia rather than a loving parent slapping a naughty child, IMHO nothing, and I mean NOTHING pays the debt for abusing chikdren and, in all likelihood, damaging them for the rest of their lives.
I like a lot of Jackson's music. My guess is that allegations against him were the result of his childhood and stilting of emotional development. I.e. he's misunderstood. I wouldn't be at all surprised if some claims were, erm, financially motivated. And he was acquitted. But had he been convicted, or if I was confident he was guilty even though acquitted, no way would I do anything that put money in his pocket from that point forward. No attending concerts, no buying of any more albums.
Paedophilia is, in my opinion, utterly unforgivable. Ever. Period.
