Man has a natural tendency to prey on other people.
This being the reason why humans must be educated
and for which we need a lot of coercive measures.

I strongly disagree.
The first sentence is utterly wrong and the second is brazenly manipulative.

Something which can be educated isn’t ‘natural’. Not in the sense implied above!
People can be educated to eat in a certain manner. As in having ‘table manners’.
People can be educated about what to eat. And what to avoid eating. To avoid eating things which are both delicious and nourishing.
People can be educated even about how much to eat!
But you cannot educate anybody to stop eating!

What is truly natural about ‘Man’ – about all people, actually – is that they need to interact with other people. In order to become full fledged human beings, people need to live among other people.

What can be educated is behavior. How to interact with other people.

People can be educated to cooperate.
Or people can be educated to gang up. And prey on those outside the gang.

Please note that those who gang up in order to prey on others do cooperate among themselves!
Even if that cooperative behavior has a strong hierarchical nature.
