He was a man we needed in whatever ends Gondor may perish in, ere the ultimate outcome, we needed Lord Faramir for the future.

So when I slew the porter, I was thinking of his larger life at stake pitying Faramir who had no knowledge of being burnt alive. I saw the madness in his father’s eyes building but my eyes were only set on my captain, Faramir. 

The halfing was right- i had to save my Lord’s life. He was still the beacon of hope for Gondor no matter what ends we may suffer in.

Let him be spared.
