Why do you suppose jefferson felt that it was not only the right but also the duty of a people to overthrow a despotic government?

Jefferson felt that it was the perfectly fine as the obligation of a people to oust an oppressive government since it is not out of the question to the general population all in all to ensure each other, else it would influence their security and joy. 

From the Declaration of Independence. Not exclusively do you have the privilege to oust your administration, it is an obligation put on us by establishing fathers. On the off chance that our legislature double-crosses us, acts other than as per our desires, or we feel changes should be made, it is our commitment to do as such.
