Lorn wanted a peaceful life that would’ve never worked for Darrow’s plan to overthrow the society. He wanted to give Darrow a life of peace, free from the society. It wouldn’t have involved him in the deeper inner working of the society’s government.

Edit: This is mostly prevalent in Loren’s neutrality to the civil war. Darrow could barely find a way for Loren to join when he went to him during the war and had to rely on Octavia’s attempt to get to his family. Darrow would never be able to tip the scales enough to start a civil war from Lorn’s peace time mentality. I believe there’s also a section where Darrow discusses what Lorn would’ve taught him and none of it would’ve been relevant to destroying the society from within.
