ok. What is it you are actually asking?

The problem with this is something you actually explained yourself "some verses it is but in other it isn't". The problem here is that many media have some form of an afterlife in which case dying is merely a step to the next cycle. For those series we need to have some distinction between death and non-existence. For example Dragon Ball is a universe that runs entirely on the concept of death is cheap (the main character's died twice) but non-existence is a whole other can of worms. You can ressurect Goku back to life with the dragon balls but you wouldn't be able to do the same if Zen'o or Beerus erased him from existence.

Blazblue actually makes a pretty great distinction between the two. Assuming Ragna died at any point in the series he would still have people to remember him but at the end of CF, he enters the Master Unit effectively sacrificing his existence in the universe. He's still alive but now no one knows who he is because he doesn't exist anymore.
