They may be right though in a way. Just because he might have been the one to physically take his own life doesnt mean he "killed himself", i.e. someone pressured him to do it or there would be other consequences, like how I figure Virgina Guiffre got done. Yeah she may have been the one to do herself in but perhaps only is outside forces blackmailed her into doing it upon threat of harm to her children.

So Kash and Dan may be playing word games in that there's no EVIDENCE he didnt KILL himself, but doesn't mean he killed HIMSELF... and for anons to dig, or leave plausible deniability etc.
