Certainly understand your/her point of view. Since her divorce from his father she would have little if any influence May have been best for TM if he had stayed with her. Biological parents have much lacking
Listening to her, she certainly sounds like a decent person. I do think she was probably quite a bit naive as to some of the other influences that were taking hold on Trayvon. If he had survived long enough and if he had stayed with her, she might have been able to help him through the stupid stage.
As well, if she had home schooled Trayvon rather than him going to the public school, a lot of things might have happened quite a bit differently.
Unfortunately, we'll never know.
