Envy is one of the forms of fear, vanity and stupidity. The worm of envy kills love and faith. Man cannot love whom he envies. The main sins of the jealous are mendacity, betrayal, subversion and so on.
The road to hell is paved with good intentions. "Do not judge," but you, full of good intentions, begin to judge and go astray and come to hell. Fair enough. The desire to judge is a sin of pride, a mortal sin.
The first road to hell is fear. The second one is lie. The third one is greed. The 4th one is avarice. The 5th one is ignorance and stupidity. The 6th one is anger. The 7th is dejection, lack of faith and dream. There are other roads too, but the first seven ones will suffice you, I guess.
