Given a premise, an initial context, an original ending, and a counterfactual context, the task is to generate a new story ending aligned with the counterfactual context and as close to the original ending as possible. Each instance consists of a five-sentence story. The premise is the first sentence of a story, and the second sentence, which is the initial context, provides more information about the story's context and the story's general plot. The original ending is the last three sentences of the story. Also, a counterfactual context is a slight modification to the initial context. You should write a new story ending that edits the original story ending as little as possible to regain coherence with the counterfactual context. To sum up, you should write the last three sentences of a story based on the premise(first sentence) and the counterfactual context(second sentence) of the story.

Premise: There was a guy who kept saying that humans can't change the world. 
 Initial Context: He meant that quite literally, that nothing we did had any effect. 
 Original Ending: He said releasing millions of years of stored carbon was fine. He was sure that industrial accidents fixed themselves. Everyone just shook their heads at his crazy ideas. 
 Counterfactual Context: He meant that politically, but he agreed we were definitely causing climate change.
He said releasing millions of years of stored carbon was terrible. He was sure that industrial accidents didn't fix themselves. Everyone cheered for him.
