Is that a serious question? If so, then I would question what you have been taught about the relationship between the Old Testament and the New Testament.
Can you name me one Old Testament saint who perfectly kept the Law? If not, I suggest you apply the same scrutiny to your own understanding that you are applying to visually_augmented.
No one was able to perfectly keep the Law. That is why the sacrifices were required. That is why the High Priest had to make a special sacrifice for the people once a year.
