Question: Why did Louis kill Church at the end? He only planned on killing Gage if he came back like Timmy Baterman did, and he could have just walked in after distracting Church with the meat.

Answer: I think he was testing whatever was in the syringe on Church first to make sure it would actually kill them.
Chosen answer: Church's behavior had changed after being buried. He was now violent (and working with Gage) and needed to be put down before killing anyone.
