What I meant was, imagine your friends and relatives dying in an earthquake and all of your stuff destroyed. Not you yourself dying.
That's point numero uno in the OP. Regardless, then you're feeling sympathy for a personal scenario, not for the other people.
And even so, I wouldn't mourn their deaths, but the loss which accompanies death, which is what everyone mourns, I think. Except little kids, who mourn death itself, because it's what they're supposed to do.
