Why humans evolved to perceive evil at all?
We are the only specie to perceive evil, justice, mortality, etc.
BTW no other species have consciousness at all..
Nope. We are not the only species to perceive evil, justice, and morality. Other species certainly do have codes of conduct as well. Wild Justice: The Moral Lives of Animals by Marc Bekoff and Jessica Pierce is a good book to read on the topic. Marc Bekoff is a Professor of ecology and evolutionary biology, and Jessica Pierce is a bioethicist and a philosopher.
The book is only 200 pages long, but it contains a lot of information; for instance, it cites experiments done by other scientists, so you can look those up as well.
When it comes to consciousness, it still remains one of the great mysteries of science. We don't know what it is and what causes it, but in the Middle Ages, we also didn't know that the earth revolves around the sun, not the other way around. Sooner or later, we will find out. The unknown is not a reason to believe in a divine entity.
