Iron is one of my favorite Sinners for numerous reasons but the non-blorbo ones are her sheer commitment to her ideals and hopes. She refuses the chance to get into a cushy Eastside job, travels to Syndicate to establish a medical center on what's basically hell on earth, manages to suppress a Mania flareup by sheer willpower and CHOPS OFF her own arm without hesitation, to help Anne and her patient.
She still helps the gangs, even the ones that literally attacked SALVA, gained the respect of the Legion to the point of being personally invited by Zoya (which is a big deal mind you) and even after declining, it's heavily implied that the Legion is helping minimize the attacks in SALVA.
The woman has more backbone than every single one of her former classmates combined.
