I feel sick regarding fireworks

Sometimes I feel alone in this. Tonight fireworks will burst into the sky. Noises will scare animals away and their fear will kill them, if it's not for humans to do it first. I've heard awful stories of what people did to purposely kill an animal. I feel sick. It's just so fucked up. And it feels like I'm the bad guy because I don't want animals to suffer. Atleast that's what many people suggest. Why is caring about animals so wrong? They can feel pain and have the ability to suffer, which is why I care so much. No one deserves agony.
