no because Katniss clearly had a big soft spot for kids and for innocence and it starts with Prim obviously her darling little sister who she'd do anything to protect from the horrors of panem and then there's Rue who her heart immediately breaks for seeing her get reaped with no one to volunteer for her and protect her
her not wanting kids was explicitly because she couldn't bear to watch them suffer the world she's suffered in or be put through what she was as capitol entertainment (she notes victors children are reaped at a suspicious rate and the thought of mentoring her own kid is terrifying)
to me knowing that she healed enough and changed the world enough that she got to bring innocence into the world and love it without having the risk of that love being a tool against her and that innocence stripped away is everything
