Yep, it seems unfair. But to further consider it... If the abuser lives a different life this time and turns out differently, is he still to blame for what he did in another life under different influences that created different circumstances? It's sort of the nature vs nurture argument. I'm just playing the devil's advocate. :)
I think something I dislike in otome isekai is the fact that sometimes due to transmigration it's not the original victim of abuse, manipulation or whatever bad thing that happens that gets the apology but the "new" transmigrated MC who actually didn't experience any of that trauma.
Makes the apology and redemption feel cheap because the actual victim is long dead and often completely forgotten by the writer. (Though admittedly there are some writers out there who do give closer to the og body's soul in someway or another which I really appreciate. )
