There's was almost no chance these kids could grow up to be decent people with a paternal figure who believed black people are inferior, that women should submit to their husbands and that gun rights trump safety, particularly the safety of children.

Doesnt justify murder by any means. I believe all people are capable of reform. Unfortunately capitalism was creating a positive feedback loop so that the more regressive ideas he spewed, the more views he got and the greater his wealth would grow. Making reform unlikely but its always possible.

Ultimately his kids may have a chance of growing up to see all people as equal now, because I doubt their father would have accepted that from them.
