This is a really sad case. Men like this target their victims carefully and often go for vulnerable people. It can be a grooming process, and they slowly build a cage round her so she can't get out. Her and her baby deserved better.
I think you make a really good point about men often not changing. Abusive men tend to be totally selfish and don't accept they're wrong, making them resistant to change.
