The Creature means that the story of Felix's efforts on behalf of Safie's father and
the ruination suffered by the De Laceys as a result have taught him how to manipulate
the judicial system. Thus, his framing of Justine Moritz is deliberate. There is a
further sense in which he has also framed the magistrate Alphonse Frankenstein to
become complicitous in a grave injustice, but that solid upright citizen is never
aware of it.
A particularly brutal aspect of the "sanguinary laws of man" that the Creature did
not learn from Felix but has discovered on his own is how to victimize women. In the
1831 text (II:16:35) Mary Shelley stresses that Justine is framed because she represents
the type of Safie who fled in fear from his presence. In the revised text, then, the
planting of the picture is a symbolic form of rape.
