I think everyone needs to agree to disagree on this one. Truthfully, I don't even think anyone is completely disagreeing. Of course the djs share in some blame. Of course the depression and previous suicide attempt show the nature of the victim as well and that has to share in some blame. Of course the media shares in some blame for blowing the whole thing further out of proportion than it had to be. Of course the hospital even shares in some blame for not having tighter security on patient information (someone just calling should not be told private medical information so easily, especially after being transferred, that's not a single personel issue, that's a full hospital security issue, IMO.)
Truthfully, the biggest culprit here is human nature. If we weren't entertained by morons like these two djs or the media that blew this out of proportion, neither would have happened. I think this is the saddest truth, all in all. Where some find entertainment, others find depression and suicide.
No one thinks about the consequences to other people anymore because of their actions. People share and spread pictures of other people with captions that mock or bully them all the time without even thinking about the fact they are contributing to cyber-bullying. It's the equivilent of someone sharing a picture of someone in high school with a drawing on it making fun of that individual throughout the school, but on a much more global scale. Think about the fallout to that individual from that! Think about how they must feel before you click that share button or forward that email next time! You can stop cyber-bullying at any time by not contributing to the spread of such filth.
