You've been wanting to unburden yourself of this information for a while now, and it's probably a good thing for him to hear. It's family history. Who knows what his mother told him about her childhood, your father, or why the two of you hadn't been close in a long time?
You didn't make your father out to be a scoundrel because you also told your nephew about his finer points, how he loved your nephews, and redeemed him in the end.
Did you tell your nephews about your stroke and upcoming surgery?
