I don't think people getting attacked and people attacking the animals are related. People just do it for fun, that's all.
Here in the US they go after coyotes in the same way which proves there are far too many jerks in this world and in every country. If only we could give the animals weapons so they could defend themselves from these monsters.
Coyotes have a better chance at escaping though. Kangaroos are just too big. They're nearly defenseless when it comes to guns.
People who slaughter animals just for the hell of it, or just to put a head on their wall, are among the most disgusting, degraded human beings on this earth.
I couldn't handle looking at those photos. I hate seeing animals being abused like this. It really disturbs me. I've never seen a kangaroo before but it appears that they are beautiful and kind-hearted creatures who should not have to go through any of that cruelty=(
