I think it's punishment enough that the DJs from this radio show are aware of the fallout, and that hopefully they've learned to stop pulling stupid pranks like this one. I am certain this woman's death will weigh heavily on their consciences. Desiring more out of it would be unreasonable, as it isn't the fault of the DJs for what happened to this young woman. She was obviously troubled, and needed help, and this incident was enough to send her over the edge. Very sad, but not a reason to bring retribution against the DJs themselves, I don't think.
I tried to make a deal with the Devil, once. Turns out I didn't have anything he wanted.
You will never find a more welcome hive of love and humility.
