There you go again, NATO is a defensive organisation and is simply there to defend those member countries against aggression or attack, Finland and Sweden are totally independent sovereign countries who after seeing Russias invasion of a nearby sovereign nation look like they now desire to join.
Why is a coalition of countries joined together for the sole purpose to defend themselves against an attack, a threat to Russia at all, unless of course if they have ambitions to invade any of the future member states, it is just like Russia is a federation of states who form an alliance to defend themselves..
NATO isn’t the big bad wolf in all of this, NATO hasn’t invaded anyone, Russia has, don’t forget that.
