How do women act carelessly and cause destruction to their peers in both Macbeth and The Great Gatsby?

Lady Macbeth causes much destruction, directly and then indirectly, in Shakespeare's Macbeth.  I'm not sure I would classify her as careless, however.  She is extremely deliberate when she manipulates her husband into going ahead with the assassination of Duncan.  She's also deliberate in her plans and attempts to hide their guilt.  If she's careless, it's in her failure to realize that once she got Macbeth started, he would order further deaths and become a tyrant, all of which turn his subjects against him and convince others that he was guilty of treachery in the killing of Duncan.  But I'm not sure that could have been foreseen by Lady Macbeth. 

Daisy, Jordan, and Myrtle are certainly careless in The Great Gatsby.  Daisy lets Gatsby take the blame for the accident then just leaves town, even after Wilson kills Gatsby.  Jordan comes right out and says that she is a careless driver, and just depends on other drivers to watch out for her.  Jordan is also amoral.  And Myrtle appears to not consider Wilson or any consequences when it comes to her affair with Tom.  Plus, of course, she runs out in front of a moving car depending on the car to stop, which not only results in her death, but in the deaths of Wilson and Gatsby.

In short, Lady Macbeth is aggressive and deliberate when she causes destruction.  The women in Gatsby are more passive and careless when their actions lead to destruction.
