We were de facto allied to Germany, even if de jure we weren't. Great Britain even declared war upon Finland a day before Pearl Harbor, though USA never did. Royal Navy Air Arm planes bombarded a fishing village at Petsamo once. Still, Finland really is only seen as "bad guys" in Russia, and that's only because of decades of Soviet propaganda. The vilification level depends on which decade's history books you look at, but basically Russians justified Winter War because Finland then joined Germany in '41. Which is illogical and backwards, but apparently works.
