When we meet Vera, the viewer gets a different representation of a woman. She's strong and very willful. She is out for herself and that's all. She's the boss and she makes sure that Al knows it.
She is completely in control the entire time, up until she tries to steal the fortune from Charles Haskell Sr. This was the first time she really showed anything other than anger and ferocity. "You hurt my hand and I'm going to get even." She isn't as strong and you can see how desperate she has become for the fortune.
Ultimately, women are represented as cruel, strong, and threatening. Vera is the only woman with a very strong role and she ends up dead after breaking under all the stress of the plan she was trying to hatch.
