The passenger list seems to say that he was going to join his sister Mrs. M.A. Smith, 58 East Clay St., Waterbury, Connecticut.
On a passenger list for the Arabic from Boston to Queenstown arriving 13 Jun. 1907, there is a Chris J. Hazel, in the wool business, Irish male adult of age 12 and upward. Also, below that, it appears to have someone listed as "Ch. Chris Hazel" and other information the same as Chris J. Hazel.
I don't see any sign of your Christopher in census or other records, so the one going back to Ireland may well have been him.
