What is Right and What is Wrong?

Sometimes I don't know what's right and what's wrong.  I observe nature and see what we humans describe as wrong.

I've seen dogs kill kittens for what seems to be no reason, other than possibly territory or natural prey drive...  Male Grizzly bears and Hippos kill cubs and young ones for the opportunity to mate...  Chimps kill each other in territorial wars...  Animals kill each other for food...

I've watched ducks up close and personal...  Ducks will pick on one of their siblings if the sibling has something physically wrong with it...  What I saw was a duck blind in one eye being chased off and ostracized my its siblings...  I've seen male ducks invade a space occupied by a couple and rape the female duck...

A lot of instinctual behavior seems to be the root of a lot of violence and what we consider to be wrong.  So is there another standard for humans?  Are we somehow above all of this instinctual animal behavior?

And when we attempt to align ourselves with the side of "right", does that mean we're allowed to punish and treat others with violence?  And isn't that violence essentially the same thing, only gilded with different labels?

I'm unsure how to define what is right and what is wrong...
