Jean Valjean Vs Edmond Dantes

Both characters influenced by a devout christian. Both get reborn from the lowest rungs of life. One becomes rich by his own enterprise, the other just comes across a treasure. Both believe in providence. One manifests mercy, the other manifests revenge. While Jean cares even for his nemesis (Javert), Edmond doesn't even care for collateral damage (Albert, Valentine). Edmond belives in burden of sins being carried to children. Redemption and altruism vs vengeance and justice. Universal love vs love secondary to revenge (Mercedes and haydee). One dies at peace vs the other realizes revenge is hollow (somewhat).

I'm ok with everything, but why couldnt abbe faria make a more positive influence on Edmond? Especially when there are few dialogues where abbe emphasizes on similar ideas as shared by the bishop in Les mis?

What do you think?
