Lee Harvey Oswald may have been an asshole but he was at least a good dad ans he wasn't racist
There are some guys who are dead-beat dads and terrible dads. They have abandonned their kids. Oswald, on the other hand did his best to raise his two daughters along with Marina. He worked very hard for them and tried his best to be a good dad. When he was in jail he asked Marina if June got new shoes.
About racism, he was a piece of work but he wasn't racist at all which is probably rare for most people in the 50s and 60s.
I'm not taking side though. At the end of the day he was still a jerk.
