From interviews I saw, she was an excellent mom.
She held the tiger by the tail for a long time and then realized that he could not be helped by her anymore. He was burning himself...and needed help beyond her capacity and ability.
She knew he was a danger to himself and I wonder if she knew he was an evil danger to others as well.
God rest her soul. It’s wrong to condemn her.
Or alternatively she drove him to madness through well-intentioned but destructive over-protection and by presenting him as a danger to others and to himself and by giving him dangerous medications.
Being dead doesn’t make her perfect or a saint. What evidence we have (medicine, speaking ill of him to his babysitter and giving him access to weapons doesn’t indicate great parenting)
There is no actual evidence that he posed any sort of threat to anyone until he was faced with the prospect of being locked up and put under state care for life for being different.
