Why does scout disapprove of jem's and dill's of looking in at one of the Bradley's windows

Atticus had forbidden the children to go anywhere near the Radley house, especially to "torment" Boo. He had gotten through to her..... yet, she goes with anyway.

Jem was not one to dwell on past defeats: it seemed the only message he got from Atticus was insight into the art of cross examination. “Scout, we ain’t gonna do anything, we’re just goin‘ to the street light and back.”
