First let me say that I do not know how anyone in the Murdaugh family could have sat through the trial or given a moment’s thought to the new timeline AM has given and not at least give serious consideration to the possibility that AM is guilty.
Second, I have family members that weren’t always on the right side of the law -though never to the extent of murder - and I watched other family members turn a blind eye to any evidence of their behavior for many years before they were able to admit that their child or sibling did what they were accused in one situation or another. So I get the tendency family has to defend one another and close their eyes to the possiblity of a loved one doing something so horrible.
Third, despite any and all questionable or unethical or illegal activity surrounding the family or the law firm, I feel sorry for all of them. Whether AM is convicted or not, their lives have forever been changed. The family has lost 2 loved ones and the partners careers have been forever tarnished by the association with AM. And whether AM is guilty or not or whether they believe he is guilty or not, does not change any of that.
