Realizing you are evil Yes, I agree. i have learned that the snake represents knowledge of the self (not saying knowledge is bad) But they then realized they where naked. Got ashamed and hid. When they later realized they could get hurt, they gained the knowledge of evil bacause they could then hurt others.
The evolution idea is interesting because young chimps petrol the boarder and if they see another chimp tribe and outnumber them, they kill them. It's like war, like we do.
Yes, but that does not make the lazy people good. If they had the upper hand, what then?
