Ugh that sucks. I can only guess that it was an oversight but you’re absolutely right to be bothered. As you suggest, likely a moment of “get this bag out of the way”. Still upsetting for sure.
While it was thankfully brief I also was part of end of life care for my Dad and despite the anguish I took great comfort from knowing his last hours were with loved ones nearby and in his own bed. I wish that the knowledge you were there and helped brings you solace in your grief. You were there when it mattered most. hug I wish you and your family peace.
