It’s simply the matter of where we draw the line. Child porn is nearly universally considered past the line. Bestiality is predominantly considered to be past the line. Videos on how to make weapons or learn self defence / martial arts (all mechanisms by which violence can be inflicted) are placed past the line or not past it in the laws in many parts of the world. Hateful and vitriolic rants will be illegal in some places and legal in others.

Is it really so hard to understand that some people draw the line between the two things you mentioned? Especially when those advocating it not be illegal, may consider the video of mass murder to be news, or audiovisual documentation worthy of preserving as evidence of the events that have transpired.

I know that people draw a line, that’s implicit from me saying that people make the distinction between those two things. What I said was personally I don’t understand why they draw that line.

They can archive and preserve it themselves, or using services that want to facilitate that, and be subject to whatever local laws may permit or prohibit that. As you said laws vary by jurisdiction.

The anger at FB for not wanting to be party to disseminating this video of a horrific crime really is hard to understand.
