Answer:
Porphyria was his all this time as though that was the ideal minute he needed to love for his entire life and the main way he ration that minute was to kill her since he knew with Porphyria dead she couldn't be any other individual energy yet his.
His "deed" was unquestionably childish. Murdering somebody to help ownership, which is the reason I think he slaughtered her, is no chance caring. "Nor could tonight's gay feast restrain a sudden thought of one so pale for love of her, and all in vain: So, she was come through wind a rain." This statement shows that he knew the power he had over Porphyria right then and there and after that when he specifies "Porphyria worship me" it appears as though he was the authority.
