Humans - Are we really unique?

[Napoléon]

That's pure instinct. But have you ever seen a cat to kill another cat because the other cat doesn't believe in "the right" god? Or because the other cat is gay?

And how do you define instinct? A lot of the first article would seem to support that humans killing other humans for, what are really arbitrary reasons, is not far off a cat's instinct to play with mice. Or other animals doing good/bad things through their own choices. Like it says, it's not so much the fact that humans do good/bad for more complicated reasons, but that any animal can do good/bad for any reason based on some form of morality. Humans obviously have more complicated moral questions running through their head, but it has been shown that certain animals seem to act on some basis of morality as well as us.
