Nguyễn Trãi
Despite the vindication Trãi was considered guilty by some historians and scholars, because of his relationships with Lady Nguyễn Thị Lộ. On the basis that killing an Emperor is an unforgivable sin, Lê Quý Đôn in the 18th century stated that Nguyễn Trãi should not be considered as a meritorious official despite his great contributions for country and the royal court during reign of Emperor Lê Thái Tổ.
