Yes you are. What else would you call it when you go out with a gun with the intention to hunt down and shoot something? You thirst for blood. You are, quite literally, bloodthirsty.
You don’t need to kill any animals to eat. You can just go to a shop and buy your meat. There’s something extra involved here - above and beyond the desire for food. I assume there are shops where you live? You wish to kill. Nothing will assuage this desire until you have tasted blood.
And it would have continued to lead a pleasant, free life if you hadn’t showed up and shot it.
It’s a cleaner kill than somebody blundering around the woods with a shotgun taking potshots from 50 yards away.
And why do you want to do it anyway? Why not just leave it alone?
