Animals keep dieing in my yard .. What the FUCK??

I only have a 1/2 acre of land with some woods behind my house but i have tons of wild life running around. we were very excited when we noticed that one of the many bunnies that hangout on my lawn had a baby in the flower box by the pool. we would go over and the little guy would look up at us. it was nice. the other day i had 50-100 black birds and crows in the trees behind the house. I went out to check on the bunny and he was gone .. all i found was a Bunny foot. I guess that foot wasn't lucky . I told the kids he grew up and left ..

Today there is a baby Possum laying next to the shed and he's still alive. just barely breathing but alive. look like a cat may have got a hold of him. I'm not sure what i should do. should i just leave him and let nature take its course? should i put him under the shed and hope he stays safe till he heals? I assume him family lives under the shed. I can't see bringing him to the Vet and I don't want to put him down but i think he's suffering.

Why are all these animals coming to my house to die .. maybe someone doesn't think this SatanCash thing is funny
