Megan Jean Haines moved to Australia from her native South Africa searching for a better life, but instead of working hard to achieve that life, her bad attitude, unwillingness to do the required work, and contempt for her patients resulted in numerous misconduct charges and a license suspension. After her license was reinstated, her conduct didn’t change. When she was told that several patients had complained about herbehavior, she made the decision to use what she thought of as the “perfect weapon” and inject the patients with insulin.
