Well this shows that you don't know how this things work. Obviously I don't know which country you are from but I see you also generalise your post so I will say this.
Ukraine and Russia war or any other way has the tendency to affect you even if you don't live in the nations at war.
Ukraine and Russia may have some resources that your country do benefit from, so due to the war those resources may either stop coming or there will be a hike in the price, also this way can be a catalyst to even bigger war that may significantly rope your country in thereby affecting you.
And the most important is human filling, as a human you should have compassion on other humans dying needlessly in a war even if you aren't affected.
