Why did I kill the Albotross?

I killed the Albotross because I was indignate that it led our ship to the North and made us thirsty. The Albotross, to me, at this point is nothing but a prey that I wanted to hunt for, regardless of its mighty god-related image. Moreover, killing them could become an entertainment that kept our crew awake during the long epic journey of coldness in the North Pole. The weather was frightful that really put us into misery. This would probably be the only way to keep ourselves fresh in mind.
