Chap.4 DL

3.) "I see no vengeance, plot no evil against thee."
I think that he is lying, there is obviously something about him that gives Hester chills. Why is he so desperate to find it anyway with out getting revenge. He seems like a very intelligent man so i think that he has a plan and when he finds out who it is he is going to break his promise with Hester and do something to the man who fathers her child. He obviously once loved Hester and he is jealous, or he is territorial and he is mad that someone touched something that was hers. But in the previous chapter Hester's old husband mentioned that the man who was married to the women was a fool to think that he could keep a young woman happy so maybe that's what he is upset about he couldn't keep his young woman happy and now he is mad that someone could.

4.) "Why dost thou smile so at me?......Art thou like the Black Man that haunts the forest round about us? Hast thou enticed me into a bond that will prove the ruin of my soul?"
Hester thinks that he is evil with this evil grin. The black man is like the devil because the Puritans think that woods are evil and the black running around the woods is the devil, like Chillingworth. See the devil runs around causing trouble which is what this man might start doing he is trying to get information from Hester and he will probably end up doing something really evil with it.
