yeah hurting 動物 is bad because think of it this way your the animal and the animal is あなた and he was kicking your 尻, お尻 how would あなた feel 動物 dont eserve to be abused によって humans
First of all... *they* have teeth and claws, and *I* have nothing. Secondly, I would never use a weapon on an animal, especially for a "fight". Lastly, again I ask WHY would I want to fight one, exactly?
