The man at the bar did not deserve to be killed
It was too harsh. Yes, he was about to rape her, however, the situation was under control. The stupid *itch had the gun trained on him. They could have escaped and then called the police. A person has no right to take another person's life in their hands, unless their own live is in danger. Yes, she was reacting to a situation that she also encountered at another time in her life, but killing someone in not a good choice.
"Duh. You're the idiot. Not me."
