You should stay and make a change.
> When the war began, some sensible Russian people had stated that they were ashamed to be a Russians. Others had stated that they were not responsible for Putin's actions, because he was always a usurper and they were always against him. I think the both sides are wrong. On the one side, it is foolish to be ashamed of your nationality, just as to be proud of it, because the origin of a person does not depend on his will. Only your actions can be a sources of your pride or shame. On the other side, unlike the legal responsibility that may be personal only, moral responsibility may be both personal and collective. Personal responsibility is a responsibility for own acts that constitute the objective aspect of a crime. Collective responsibility is incurred when a persons have not done all measures within their power to avoid the situation in which the crime is committed on behalf of society of which these persons are a part.
> Just some examples. Anna Politkovskaya and Boris Nemtsov are not responsible for this war, because they resisted Putin's regime, fought for Russian civil society, and, as a result, gave their lives. Alexei Navalny is alive but he survived an assassination attempt, was imprisoned and is still fighting Putin's regime, so he is not responsible for this war. Yuri Nesterenko is not responsible for this war too, because he distanced himself from Russian society in advance, stating in 2010 that Russia was always absolute and pure evil growing out of mentality of Russians, and he had for ever left Russia and was granted asylum in USA.
> Quite simply, if you want to avoid the collective responsibility you should stake your life on the line fighting for your society and become a hero or sever all ties with your society in advance and become an outcast.
> As for me personally, I have not severed all ties with Russian society and I'm alive and even not jailed. Therefore, I share collective responsibility for all what is going on now.
> My beliefs have evolved, and there are some things seemed right earlier but not seem right now. I was constant in one thing – in categorical opposition to Putin's regime. I always believed that the expression of discontent is not enough, because words don't change the world. I carried out actions using all tools available to me. I was a lawyer (even good, in opinion of some people) and tried to uphold the law, rights and freedoms, not just as a representative of a party to the proceedings – for money, but also on my own behalf – for an idea. Fight for an idea has brought nothing but problems; however, I knew what I was about. I wasn't naive man, I saw dictatorship, a priori incompatible with justice, was being established in Russia, but at that time I felt obliged to use all available legal arrangements. However, in 2020, after the amendments to the Russian Constitution was approved, I realized that I finally had enough. The country where the law was replaced by schizophrenic delusion of psychotic führer, really doesn't need lawyers, and, under these circumstances, I considered it shameful to continue to pretend that well-written legal document has any meaning. I saw that elections, mass protests, petitions, legal proceedings didn't work. I saw that attempts to change the situation through a violence against government structures (see this) did not work too, because it didn't resonate with society. I don't know what I should do now to change the situation. Anyway I realize that all things what I did earlier were inefficient - I haven't prevented the transformation my country into fascist dictatorship. And so, again, I share collective responsibility for all what is going on now.
Cut the crap. We are all part of a single society - people of the earth. Follow your logic we should be doing nothing else but trying to stop the world acting the way it does. The atrocities are everywhere. I would not be able to sleep and function at all if I've felt that "collective" responsibility. This is not how humans work.
When Putin captured all the power in the country, rigged the elections, killed journalists no one cared at all. US, EU, UK, etc - no reaction at all. War with Georgia - no reaction.
When Russia actually started this war 8 years ago and annexed Crimea there been really weak reaction and after everyone just did business as usual. EU even sold Kremlin equipment to fight protesters as well as military weapons on condition they will only be used "inside the country".
When Russian opposition leader Navalny was poisoned again no real sanctions were introduced. Now US, EU and UK expect people to go on streets and protest.
PS: I am from Russia and I immigrated to Turkey on 25th of February and there is nothing fun about going into unplanned political immigration. I dont try to remove all responsibility from myself or someone else, but even I as software engineer have very limited capacity to do political activity. Since I have a job and my family to feed.
Now from abroad I help my friends from Ukraine when I can and I publicly share my political statementa that will land me to prison if I ever come back. But sorry I'm not going to destroy my life for the cause.
