Life is a form of trauma. Noone gets out of here without experiencing suffering. Topic has been discussed in other threads : Many contributing factors play a role in a parents' CTB and few of these are scrutinized / judged as 'traumatic'
Whether it's a job loss, divorce, unfavorable treatment in court, grief from separation from kids, grief from loss of house, etc these things play a role in CTB of a parent and trauma to minor children should be minimized...
I presume in my case the cunt they call their mother will lie about the cause of death and it will not be discussed until they are much older.
