The world of animal Vs The world of Homo sapien

I had just viewed dobot's blog and what he said caught my attention. He said :
Di dalam dunia binatang tiada manusia, tetapi di dalam dunia manusia ada binatang. Malahan, manusia lebih teruk daripada binatang.

Dalam binatang tak ada yang buang anak sendiri. Dalam binatang tak ada yang bakar bendera Malaysia. Dan, di dalam binatang tak ada yang masukkan timun dalam buntut binatang lain (referring to the case of Nurin Jazlin)

How true it is. In the world of animal, there is no human. They show their true behavior, desire and do what they wanna do. They never know how to cheat, to threaten people who is kind. But in the world of the human, we even dare to harm any even the same species.....so call Homo sapien

Sometime, we treat all the animal bad, thinking of escaping from them, or killing them every time we feel we are threaten by them. But, who is who's enemy? Are they threatening us or the other way round? Are we the lord that can ignore the value of other creatures in the world?
