How does Sheila show social responsibility?

"How could i know what would happen afterwards ... it did not seem to be anything terrible at the time" "It was my own fault" "I had her turned out of a job.I started it" “I’ll never, never do it again to anybody" At the beginning, Sheila didn't seem to take responsibility for what had happened. She showed how we need to realise that we won't always be able to predict the significance of our actions. However, later, Sheila takes responsibility for her actions and tells the truth. She's 'miserable' and owns up for her wrongs.
