good points servant and jgnat,
and again, the animal kingdom is replete of examples where 'good' actions take place - animals can show affection, 'love', care and compassion, mourning. animals will defend their own with tooth and claw (literally), even sacrifice themselves for their young ones or the weak.
animals are also capable of feats of engineering, teamwork, productivity, communication and even language comprehension (talking to each even, ex. whales)
BUT, they also display the aforementioned 'acts of evil' because they ARE animals after all.
yet, the very same actions among humans are not 'nature', they are evil.
and so i beg the question, why is this? and are we honestly different?
