What do you all think about late apologies?

In the rare cases where someone apologizes for cheating on you 10 or 20 years ago, hurting your feeling at your past workplace or bullying you at school... what's the point of it?

The damage has already been done, is there a point of delivering a late apology? What do you think of those cases, where you get an apology from someone that hurt/wronged you 10+ or 20+ years later?
