Fyodor Dostoyevsky said this quote

For know, dear ones, that every one of us is undoubtedly responsible for all men- and everything on earth, not merely through the general sinfulness of creation, but each one personally for all mankind and every individual man. This knowledge is the crown of life for the monk and for every man. For monks are not a special sort of men, but only what all men ought to be. Only through that knowledge, our heart grows soft with infinite, universal, inexhaustible love. Then every one of you will have the power to win over the whole world by love and to wash away the sins of the world with your tears.
