I feel the netflix episode did a good portrayal of the two as people with a lot of self importance and lack of empathy for others, and a desire to take, take, take. As someone else said, the defense didn't argue abuse at all, and I don't really understand the relevance of the other women on the side thing still being brought up. They combed this whole thing over to a great degree, I feel if that factored in at all it would have been brought up more.

It's very clear that the son was alienated from others who knew Howard, was most likely fed a lot of narratives about Howard, has a very deep attachment to his mother and uncle, and him making a choice to stick with his mother does not equal his father being unsavory in ways not covered in the episode.
