Differential emotional perception

A theory that defines the normal humanbeing in her normal state. Where the death of a cockroach does not elicit the same emotional response as the death of a child. They are both deaths-- and deaths are regretted in general because they are a form of loss. But context modulates how we emotionally perceive the death. The death of a cockroach hence is met with a curled lip of slight disgust. (Who is going to clean it?) The death of a child (if a stranger) is met with a furrowed brow; depending on further details of the death, may provoke a tear or two. And certainly it will make us think -- how fragile life is. And if the child is familiar, we may emotionally perceive the event with a strength that is apt to blind-- never to recover fully ever.

A theory that also has a footnote --
Under changes in her internal environment (induced by potent forces), a normal humanbeing forgoes her normal state and loses her differential emotional perception. The death of a cockroach is as heart cramping and gut wrenching as the death of a child.

And who to listen to all this but a good friend who is sane?
