Did Salman Khan harmed or helped Aishwarya’s career more?

Some people say that Salman helped Aishwarya’s career by recommending her to SLB’s HDDCS and her affair with Salman bought her to limelight. All her movies flopped before HDDCS except Taal and there were rumor of her of going through casting couch with Subhash Ghai. Heard from many people that Salman saved her from Subhash Ghai and that he slapped Subhash Ghai to protect her. On the other side, some people say that Salman tried to destroy Ash’s career by harassing her and going to her movie sets often. She got kicked out from SRK production movie Chalte Chalte when Salman kept coming to the set. However, it doesn’t seem like Ash career was affected much. She still worked with superstars like Hrithik, Sanjay Dutt, Akshay Kumar and Ajay Devgan and she also got some big banner projects. So I want to know if Salman really helped Ash career or harmed her career.
