Chazal say that an angel tells a fetus that even if the whole world is telling you that you are a tzadik - היה בעיניך כרשע - You should be like an evil-doer [a רשע] in your eyes.
Why?
The Tanya teaches that as long as a person has a yetzer hara - he is called a beinoni, a mediocre person, even if he never actually sins [sinners are רשעים...]. But he is having the same battle as a רשע. So he is not actually a רשע but כרשע - like a רשע. So if people tell him that he is a tzadik, he knows the truth. On a deeper level, the animal soul is still active.
Upshot: Humility!:-)
