“Tragedy plus time” is the standard formula in that vein of humor.

Let’s give the victims time to succumb and their families time to grieve before breaking out the glib cynicism toward other peoples’ lifesaving actions.

Let different people deal with the situation in their ways without playing the mighty judge who owns the "one right answer".

Maybe humor isn't negative, but I don't see how a misleading "joke" is a worthy comment. If you just want to make empty and meaningless jokes, perhaps there is a better forum for it.

I believe there is a better forum for virtue signaling, too.
