Frank loves violence. Even when he is not killing children or animals he is enacting make-believe death. Although dam building is ostensibly less violent, it is similarly about power and control. Frank recognizes that water is more powerful than he is, or will ever be, but he still gets a thrill from momentarily diverting it. Additionally, Frank’s construction of miniature villages fulfills the same violent, sadistic urges that cause him to blow up toy soldiers when playing war.
