She testified that there were herself, here best friend and 3 other people there, two had her in a room and one was trying to rape her and possible kill her. She escaped the house leaving her best friend inside with 2 rapists and a potential killer.
Lets pause there.
Leaving her best friend to be raped and possible killed without going to the police to try and save her best friends life. This is what she testified she did. She has never expressed remorse is the abandonment of her friend to leave her to be raped. If what she said was true, then she did leave her friend fate in the hands of rapists. How can anyone carry that burden in life is beyond me. Better to be a liar than to be someone whom left your friend to be raped and murdered without ever lifting a finger to try and save their life.
Nothing she can say beyond that point has any meaning about her character. She has never expressed any remorse to commit such a despicable act. It is not relevant that no harm came to her friend, only that in her mind this is the condition she abandoned her friend to the fate of rapists.
