Yeah, it's pretty bad.
One would assume people would put the existence of the species ahead of money/glory of the horn/hunt/whatever, but history and indeed present time has shown that human nature, and pretty much any other type of nature, isn't very pretty and is generally an all around cruel thing.
Sad and unfortunate, but if this species died out, it would be part of a gigantic list of ones who have already come and gone. Around 100 species (you'd have to Google for a closer figure) die each day for one reason or another. Isn't that crazy? 100 a day (some say more). Sure makes you think.
It sucks, but man, that's just how life goes (hunter-predator/disease/illness/change in habitat/weather/whatever), species just die, and someday we will too.
