Do you believe a non-human animal can be evil?
No, but they can be heroes i.e. Harambe
If we define torture as evil, then cats can be evil. I have witnessed a supposedly normal house cat torture a mouse it caught. The cat cornered the mouse, batted it around and dug her claws into its back. Then she would sit back and watch until the mouse tried to escape, then back to the batting and clawing routine. She kept this up for several minutes until she apparently got bored and finally bit and killed the poor thing.
Try and baptize a cat.
I do not believe its in their DNA. If abused or sick, they will act badly.
I'm not sure, but whichever the answer, I think it's the same for us too.
Possible. I think cruelty has been observed in chimps.
Spiders, man. Too many legs.
And snakes. Too few legs.
