The complete lack of empathy or concern for her victims, contrition or anything is amazing to watch.
This lack of belief that she would ever be found out or anyone would care about her lack of concern for people was her downfall. She could have just bailed out before the Walgreens deal when the whole thing was obviously not going to work and failed in the normal way that science project startups fail. She could have then married the rich guy and had the two kids and lived a dull life maybe selling diet pills or whatever, but she just had to go all in to the fraud and wreck her life because she thought she could just power through on delusional belief alone.
