In the Webster's Third International Dictionary, 1976, the definition of hoosier is:

In the Dictionary of American Regional English, the definition of hoosier is: A hillbilly or rustic; an unmannerly or objectionable person.

Answer to above: If the Bliss character is Roman Catholic, then it is a logical response, as the RC enumeration of the Decalogue has the Murder Commandment as the fifth.
