Ok, ok :)

It's just an argument I've seen people make sometimes - that "evil" is a cartoony outdated term associated with "religion" and "simplistic thinking", and we have evolved beyond that or whatever.
So I thought.. but yea :)

It has animal instincts and reflexes as humans do but it has a very different sense of society (if any) it has a very different sense of self and empathy (if any).

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.
