Did the giant squid live they caught?

I just dont understand people. The news of the New Zealand fisherman catching a giant 990lbs squid.. So im looking at the pictures and it looks like they caught it- drug it in on their boat- and took pics- but it wasnt what they wanted to catch so- did they throw it back or did they kill it just to have it as a trophy? If something was so amazing about it why wouldnt they tag it and put it back? Sometimes I think Man does some stupid stuff
