Sorry, I don't understand, could you clarify the c. f. part?

I mean it as an observation. When Pat Robertson died it was not a murder, so the moral problems with encouraging violence are not involved. His death objectively made the world less hateful. His propaganda stopped and other people with less skill and less of a following stepped in to replace him, but it was an overall reduction. I think it is fair to say that in that situation his death was good for society. That doesn't mean we should not fund gerontology and research how to keep older people healthy, we should be trying to prevent harm wherever we can. He died of natural causes at 93 so nobody shortened his life, it is morally empty.

When Kirk died the same change in the world occurred. His death meant the removal of the propaganda he was spewing. In the same way as with Pat Robertson we should not cause more of this type of death, in fact we should avoid and prevent as many as we reasonably can. That said, his death reduced harm and that reduction of harm can be celebrated.
