Answer:
The main idea is that all groups of people will always find a way to abuse power and oppress those that do not belong to it.
Step-by-step explanation:
In this quote, Hamilton expressed his doubt in humanity and it’s kindness. He believes people will always find a way to torment groups they belong to – big groups will oppress the minorities and find someone to exclude from the society, while small groups of powerful people will abuse the power over the many.
This second is especially relevant in the monarchy where one person has inborn power over the whole group and can abuse it any way they want.
This is why in the continued quote he says “Both, therefore, ought to have power, that each may defend itself against the other." This means that both people and the government should have some amount of power. The monarch should not hold all the power and oppress the majority of people, but the government also needs power in order to put the laws and protect the minorities.
