It is interesting that, out of all the questions you have listed above, none of the answers are given to us in the text directly. Instead, to find out these answers, we have had to infer the responses from the information given by the text. The inferences you have made are based on your ability to pick up on indirect characterisation, or the ways in which characters are presented to us based on the observations you have made about characters and the kind of people that they are. This of course requires more effort and brain power than simply being given the information by the narrator.
For example, based on your first question, we are not told why Mrs. Jones does not call the police, but we can see from what she does for him later on that she is concerned above all that Roger leaves this situation having learnt right from wrong, because Mrs. Jones recognises that the police would not be able to teach him this.
