What is Chilllingworth sin in the scarlet letter?

Answer:
Chillingworth is Hester's Husband.

He doesn't want the towns people to know because he will be labeled as the sinner's husband that no one knew of. So instead he changed his name to Chillingworth and is in town to find the man who impregnated Hester.
