Kengle's complaining about the fundraiser Chris requested to move Barb out of 14BLC, and the recent letter where Chris basically spergs about not being able to return home, and how Barb probably should be dead soon due to her age. The recent letter gives these undertones that Chris values returning home over the survival of his own mother, which in all honesty, is something I would have imagined him saying if he were in jail for a crime like this. For some reason, people like Kengle interpret it as him "wishing death on" or wanting to physically harm Barb.
