Sometimes, great people die. It's sad, but it happens. Usually, though, the loss of a great person just means that person is gone. That really shouldn't be a problem, right? If you're a great person and you die, it just stands to reason that other great people will carry on your legacy.
Sure, in a perfect world, that's exactly what would happen. It doesn't, though. Instead, more often than not, when a person dies, the end result is that the thing that their last name is the same word as also disappears.
