There is no war that can be good. Of course, it is an individual matter whether someone wants to support the boycott or not. The boycott and sanctions are perhaps the most peaceful attempt help in stop the war if the aggressor doesn't want to stop it, so in my opinion this initiative is good.
Every war will have consequences for both parties, whether it's the loser or the winner because they both lost their soldiers who had defended the interests of the warring people. Boycotts and sanctions might help but in this case, the Russians are likely to survive because they have the resources at their disposal to help them survive. We don't know when the war will end, maybe it can last until the end of the year or next year. We can only hope that the people of both sides will survive and that the leaders of Russia and Ukraine can communicate to end the war soon.
What currently happening is battle between the pride of their leaders and its really unfortunate that other life has been sacrifice for what decision they made. Look at what happen to them now both of this country economically struggle due to the incident happen to them. And I guess sanctions will not help this case anymore since as we see Russia became more aggressive even if there's something like this implemented on their country.
