Why do photographers always take pictures of people before they die, but don't save them?

There are many photographers who take photos with telephoto, that is, the photos look very close, but they are not that close. It's really impossible for photographers to rescue them.

Of course, the utilitarian mentality of some photographers is not ruled out. It seems that dedication is really ruthless. Judging from that work, the weight of the photo is even heavier when the person in the work dies.
