Cats have been observed to show grief towards other cats (who dieded) and, I think, humans, too.

Generally, I'd consider a cat more capable of "evil" than, say, a spider (those have been observed to vary in personal behaviors, but you couldn't call that personality).
Advanced animals already have the same recognizeable instincts of empathy, aggression etc., but you can't blame them for failing to apply moral philosophy to their actions, that I agree with.

It would be impossible to draw much in the way of meaningful conclusions about cat self image/empathy etc without being a member of catkind (which we routinely physically castrate to prevent the evil smell of their spray, though some people believe that to be an evil practice).

It's difficult enough to do that with humans but you can at least learn to listen and ask questions in their languages...some of the time.

And in answer to your previous question there have been many cultures that would deem a goatee beard wearer evil.

And others that see it as evil not to have a beard (ladies mysteriously are exempt from these rules).

As far as we can tell a cat is no more capable of being evil than say an olive.

Neither are human, neither can be expected to understand human morals, ethics or laws.

But humans can believe them to be agents of Satan which is of course as probable as a human being an actual agent of Satan.
