I couldn't help but note an undercurrent in this thread, something I've encountered in my own practice. Somebody takes ill-conceived action in a tree which results in their demise, and suddenly the tree must be removed.
If the decedent was in the process of removing it, by all means, engage a competent technician to complete that task in the name of public safety. If, however the intent of the deceased was not the removal of the tree, why do their grieving families often insist that the tree must also die. Should the unfortunate death of a loved one be commemorated by killing another organism, which was completely without blame, and which manifested no malice? I fail to see the morality in this, and I think that, as providers of tree care, we may have a duty of care to at least give an alternate perspective, and perhaps avoid a needless second death. Pragmatically, the hole in the hearts of their family, will not be filled by an empty space on their property where there once was a tree.
In once instance I know of, a troubled youth hanged themselves in a tree on family property in a municipality. In another, a fatal collision occurred when a speeding driver lost control of their vehicle and crashed into a city tree. In the first case, the family insisted on removing the tree and the city gave them a permit, no questions asked. In the second case, I opined that, although significantly damaged by both impact and fire, the tree would likely recover. The city arborist was skeptical, but decided to let the tree remain. Thirteen years later, the tree stands with hardly any remaining evidence of the original damage, and society as a whole, seems not to be any worse off because the tree is still living and growing.
People in anguish will often make impulsive and rash responses, just to feel as though they have taken some kind of action. I think as professionals, though we should at least look for opportunities to gently engage with bereaved tree owners in situations like this and to present an alternative to "a life, for a life", where the second life is a non combatant tree.
