As in the previous question, the Haggadah mentions the wickedness of Lavan that surpasses the wickedness of Pharaoh.
THat wickedness seems inconsistent with the general story of the Torah - Eisov was wicked because Yaakov was good, but Lavan comes from a good family (Rivka's brother).
So how come Lavan turns so evil and how come nothing bad ever descends from him and how come he's not punished?
