Morality is a human construct. Nature has no morality, only survival matters - by any means. That's why such cruelty (from human moral viewpoint) is found in Nature.

>Nature has no morality

But perhaps it does? Animals kill other animals only to survive (to kill them in order to eat them or to defend themselves from being killed/eaten)

Humans may be the only species who hurt other humans just for the fun of it - now _that_ is cruelty.

Humans and cats, actually.
