Death of K-pop star Sulli prompts outpouring of grief and questions over cyber-bullying

Sulli was one of only a few celebrities to be publicly pro-choice when South Korea legalized abortion this year, was open about her own mental health struggles and insisted women shouldn't have to wear bras if they found them uncomfortable. Those actions won 25-year-old K-pop singer Sulli praise -- but also made her the subject of harsh online criticism.
