Another thing is that the way he acted when he thought that the dead man’s heart was still beating. One example was is that because the man was nervous when he was sitting with the police, his heart began to beat fast and caused him to act weird. His weird actions were caused by the beating of his heart, he was being disturbed by it. Another example is that because he is mental, he thought that the dead man’s heart was still beating. It is impossible that the heart was still beating because he was cut in pieces and it wasn't possible because the brain is disconnected from the heart. My last example is that because the beating of the heart was bothering the man so much he ended up confessing he killed him. The man could not stand the beating
