Sadly, it's survival of the fittest.
Human beings always forget that Homo sapiens sapiens appeared 200,000 years ago at least.
And like other primates, the first goals were :
-For males: being strong, muscular, having symmetric features, white teeth, being able to fight against competitors in order to reproduce the most they could compared to others competitors. Social status was important as well since the chief of the tribe had privileges and had more children than others.
-For females : having large hips so that birth went well, symmetric features, white teeth, ability to protect their children in being tough enough, eating enough. Social status mattered less than for males. The ability to take care of the stewardship was also taken into account for reproduction.
As modern human beings, we've forgotten that such as all other animals, we're hyper competitive, individualistic (especially for men) and extremely violent if necessary. And in my opinion, that's why we're so neurotic nowadays. Society or politics can't change our human nature.
Today the competition just changed its nature and is more sophisticated : instead of beating up other guys to reproduce more, it's all about social status, money and looks. Angelism is a fantasy.
Yet, we could argue that the Christian civilisation appeared 2000 years ago. And the latter reduced our biological instinct in introducing the concept of "you should not kill, rape, or steal." There have been several civilisations before Christianity, but it was the first one to introduce the concept which went against our primitive instinct. Since then, our civilisation has evolved and in the West, which used to be traditionally Christian, atheism is becoming more and more widespread. What's next then? Do we come back to our barbaric instinct? Do we try to find something else, knowing life doesn't have any meaning?
Do we, perhaps, instead of becoming barbaric again, try to legalise euthanasia for people who want it as civilised people - if we're still civilised people? So that their unbearable pain could come to end if it's their choice.
What a long post, I think I haven't done so long a post before,
