She actually really enjoys it!! She grew up extremely poor and was constantly looked down on for her gender when growing up and trying to work "mens" jobs, so she channels all that anger into her hits. She has a strict rule of no children (which her bosses don't push) and she finds the entire process almost,,, therapeutic? Most of her targets are socialites or government workers, so they people who she killed doesn't weigh on her too much. Theres nights she considers herself as a monster for being able to do her job so,,, carefree i suppose? but in the end she enjoys it and knows she's keeping those she cares about safe
