The Scarlet Letter- Characters and Themes

[lehcar]

I need to relate the three main characters (Hester, Dimmesdale, and Chillingworth) to each of the following themes:
1. Revenge destroys both the victim and the seeker.
and
2. We must accept responsibility for our actions or suffer the consequences.

If you could help me out with any/all of this, that would be great thank you!
