The statement from Chapter 4 of The Scarlet Letter that best explains Roger Chillingworth’s disinterest in seeking revenge on Hester is the following one:

We have wronged each other.

He states there that he is aware of the fact that she did something wrong to him (ran away from him and had an affair with another man) and that he did something wrong to her (wanted to destroy her lover), and thus they are even. He does not wish to continue hurting her because she lost everything once her lover died.
