Jane is shown to be somewhat egotistical as well and openly reveals that she hates being judged all the time, mainly by her father and can also be somewhat ignorant as she at first believed she did nothing wrong when she pretended not to be dating Jesse even though his feelings were crushed though she later apologized, showing that she is capable of realizing her mistakes.
After Jesse was denied a large cut of money for selling methamphetamine by Walter White, Jane demonstrated a darker and more ruthless side as seen by blackmailing Walt into giving Jesse his money under threat of revealing his criminality to his.
Jane comments that she was being metaphorical and it is a terrible philosophy, and she also tells him that it's better to make decisions for yourself.
