No Mizu, as Roy said, I agree that a death of a researcher in the field is a dreadful loss. He was harvesting cuttlefish eggs for research purposes, it's not as if the cuttlefish are on the brink of extinction and he was depriving the marine environment of a unique species, or he was doing this for trivial or fiscal reasons. The poor diver's family, friends and colleagues are going to devastated by his loss. I'm sure he knew the risks when he went diving and was victim of an unfortunate set of circumstances. Perhaps his work was geared towards cuttlefish conservation and would have been of long term benefit to the animals?
I can find no satisfaction whatsoever in this tragedy, no matter the appreciation of cephalopods.
