Regardless of new worthiness it's logical to focus more on negative things.
Negatives are problems to be solved, if enough people care maybe they will be solved too. Whereas positives don't need solving (though can still be good to think about to avoid throwing out the baby with the bathwater when addressing a negative.
Of course not all negatives can be solved themselves. If it's "X was killed due to Y" then of course X is dead so nothing more can be done for X but maybe we can prevent issue Y killing someone else Z in the future.
