There is no good or evil, only interests, nature and interests! From the perspective of biology , when you are not born in the womb, you will obtain a lot of nutrients from the mother. At this time, if the mother does not obtain energy from the outside world, you will invert the lack of nutrition.
If people do not accept social education and put you in a natural environment, will your first task constraint still be the current law, civic morality? No. Your first constraint is "death". Of course, you will find food and habitat regardless of everything. Just like animals, this is the nature of human beings - animal nature.
: The savages in the movie, they have not been educated in the human world, do they have morality? When entering human society, is your morality really "good"? no! It is an external constraint. If you do not abide by some human laws and regulations and civic morality, you will be punished. Then you will not be hurt for yourself and you will definitely abide by it. This is the reverse benefit.
People will be praised and rewarded for doing good deeds, which is also a benefit. If you do good deeds but cannot receive recognition and praise from others, will you do it? Some people take risks to make black money, which is also for the sake of profit. So after all, it is a natural interest, it just depends on the way you choose to obtain it.
Goodness is subjective and we define it artificially. There is no absolute good or absolute evil in the world.
