Do you think Kevin Federline hates Brit, or is he just concerned for the safety of his children?

I just wonder what the situation between Kevin and Britney is, I know that I personally have never been able to just emotionally shut someone out of my life after a breakup, so I wonder if he at all feels sorry for her and still cares about her, or if at this point only cares about his kids and/or money? what do you all think? I am bored and saw she lost custody so I decided to ask, lol
