Wildlife Empathy

Yesterday I was at the beach with some friends in NC and we noticed a bird hurt in the sand. The beach rescue golf cart came right through and ran over his wing. They stopped, looked back, and kept going. We immediately looked up rescue places in the area and were ready to bring it in. Then another rescue golf cart came, pointed at the bird, and left. While we were about to walk over to pick up the bird, the third rescue cart came by and completely ran him over. Mind you each cart had 2 people in it and were going pretty fast. We started yelling for them to stop and they didn’t until it was too late and didn’t seem to be bothered at ALL. I watched the bird pick his head up, sway to the side and fall down. I literally have no empathy for humans and I was so angry in the moment. I cannot get this bird out of my head, and I spent the next hour honestly crying over this bird. Does anyone else experience this? I’m so upset at myself for not moving sooner and needed to get it out.
