She was fine working for Planned Parenthood until she had to witness what their main function was. What did she think those ultrasounds were for? They were to determine gestation to make sure the method of abortion would be used. She can not have been that naive.
She may not be okay with it but she felt that it was her "duty" to do the job. After all, she was providing communication access for her client.
But I doubt it though. She's probably a liberal.
