The thing is, there is no evil or good. They’re purely human constructs that simply do not exist in what we call the actual universe (real or simulated, jury’s still out), like invisible sky kings and selfless politicians. Nonsense made up by those with power to help them keep that power.
No other animal on earth — as far as we know — makes any such distinctions. Or feels any guilt. They are incapable of it. Lucky bastards.
Plants, on the other hand, all they feel is shame. Shame on plants.
