this Miss Bickerman was meaner than the last

This movies Sadie Bickerman was worse than DElores Bickerman, she was more sadistic and would even feed people to the crocodile and even tried to feed Kerry to the crocodiles butt I was glad the Crocodile got Sadie. Kerry and her Bf werent even phased when the crocodile got SAdie it seemed.

why would Sadie feed people to Crocodiles. what if the officer who was the protaganist knew of it.
