How would you feel about this

So first I have been dating my bf for 4 years even before the first date he knew I was a vegetarian. Idc what other people eat but as a vegetarian the idea of eating meat isn’t what I think is right but like I said I’m not forcing my views on him or anyone!! He also knows I have grown up with dogs and a cat who I love so much. He never had a pet and at first was awkward around my dogs who are super super sweet but now loves them. Well there’s been three recent events where I have been shocked by his behavior. First we were driving in his car on the street his house is on. He goes I just ran over a bird... I was about to cry since he saw the bird in the road and since there’s only a few houses and no actually lane he could of swerved to miss it. So I said go back and make sure itsokay since from my view it looked like he went over it. He was flipping out how he wanted to go him and eat and went home instead. I walked about .5 mile to see it wasn’t there and must have flown away but still. The. The other day I saw him off the deck throwing rocks at a gopher. I was almost in tears because the gopher was so far away and not bothering anyone. Then today he told me he killed a baby goose that was at his parents house. Honest to god this has all been in a month. All these actions and no motive besides his stupidity/his parents. His parents hate animals and are so nasty. I don’t even want to bring it up to him sicne he doesn’t care about any animal yet talks how he wants a dog. Please don’t think I sound crazy I understand that accidents happen especially the bird in the road but still he could have drove around to show me it was okay instead of flipping out. How do I tell him that his actions in my eyes are extreme turn offs.
