Problem with most people, including myself, is that we have enough worries right before our nose; we don't have the energy or willpower to engage in troubles beyond them.
It is also how we cope in a growing insane world, where extremists train children to kill, deranged world leaders still think nuclear threat is a good way of negotiations, children are being traded as slaves and sex objects, and, yes: endangered animals are being hunted for their believed aphrodisiacs or the sheer thrill of it. We shut it out and don't think about it on a daily basis because it is just too much..
Then we get a reminder like this, and we just have to react, because not reacting would mentally be even worse. Are we guilty? yes.
But more than the common man, the world leaders are exponentially more guilty, with the added power they have to actually do something about it. But I hear the UN has turned a semi-open eye on this case and are actually doing something. We'll see what happens.
I sincerely hope the UN is *not* looking at this cat-killing-monster-dentist case; they have genocides to deal with..
