Explain whose sin is worse: Dimmesdale's or Chillingworth's and what each of their sins is.

Note..... I don't think the above answer cited that Dimmesdale's sin was adultery (thus, Pearl's bith). Chillingworth seems to indulge in most sins in his attempt to destroy Dimmesdale; Chillingworth is evil; period. Whereas, I've always considered Dimmesdale's biggest mistake the sin of ommission. How much different their lives would have been had the small family been able to be a family.
