What is a good thesis for an essay regarding perversity in "Where are you going, Where have you been? and "A good man is hard to find"?

One way to address the issue of perversity regarding these
two stories is to consider scenes that are designed to make readers uncomfortable. In
"Where are You Going, Where Have You Been?" the scene in which Connie sees that Arnold
Friend wears some kind of lifts in his shoes to make himself appear taller shows that he
is dishonest and also very insecure. That she still feels an odd attraction to him shows
how insecure she is as well, and how confused, and is a perverse portrayal of sexual
ambivalence.  In "A Good Man is Hard to Find" we feel deep sympathy for the protagonist
when she is humiliated and betrayed by a man she thought had romantic feelings for her.
His removal and theft of her artificial limb is sadistic and perverse, a sad commentary
on her loneliness and vulnerability.
