I mean for the record, her father worked as a captain for the Obvious Bad Guy Valuan Empire in Skies of Arcadia. And she doesn't seem to have any beef with them (weirdly enough they give Piastol a bounty even though she's basically a pirate hunter for them...) I imagine she understands and respects factions that stand for Order, and obviously understands the value of military might.I understand that Piastol is the only mystic hero around and I'm not saying we should throw her away, but I do think we should be prepared for the possibility she discoveres that hey, Eggman ain't a good guy and isn't really better than pirates.
There's a difference between a ship being shot down during a war and a ship being shot down and looted by greased-up boat monkeys. If her father got shot down in a war (and she wasn't like, on the ship when it happened) she probably would have grown up, still hating them but not quite as consumed by rage. I imagine if we let her continue her crusade and also, ease up on the war crimes, she'll probably be fine.
