I would like to point to another perspective on what is happening. Like most, i hope, i try to make my views fit to the events that have/are happening rather than them being defined by my views.
It seems that the protestors have no other clear goal in mind except joining the EU, this is very hard for a country like Ukraine where many people daily cross the border on their way to work, what happens to them does not concern the protestors.
I wonder if there are Russians living in the west part of Ukraine, how violently would the protestors deal with them. Because it seems that the protestors are driven by their hatred towards not-signing the deal with Russia instead of EU.
Also the current government of Ukraine has support, it is not like the whole of Ukraine has risen against it. But it is interesting that the ones who did in their lines have nazi supporters. Still one thing is clear, Russia EVIL/BAD, EU GOOD.
Since these protestors are a bit on the violent side, what would happen to a Russian or an Ukrainian who supports the government in the protestors control area? They would probably feel their hatred on their own bodies.
This is not the first time that something like this is happening.And the EU/USA always support the more radical parts of the society(with media, weapon support etc..) often leading to ethnic cleansing, and suppression of rights of some group of people. As in case with many countries where the west supported someone. Iraq, the radicals are taking how many lives per year? Libya, how many are suffering now since the intervention? Turkey and Kurds.Syria, somehow the people who eat their enemies hearts got supported by the USA/UK/GERMANY/TURKEY etc, and then they did not go in because of being outsmarted by the Chinese and Russians, but somehow the media already twisted it to seem that USA did not go to war because of Obama.
The nations that have lived under sanctions placed by your politicians, under governments who pushed for your interests and promised growth and progress... The only thing that grows is the hatred.
If EU really practices what it speak, as it obviously does not, and neither once are/were part of societies supported by the west tolerant towards their fellow human,even if many years have passed. Are the 'evil' that had to be fought against. One only needs to check on the rights of Serbs who are outside their ghettos our country. Who do not even have the right for their written language.

The only thing EU needs is workforce, destroy Ukraine so they can get more workforce/consumers who are capable of sustaining their own economy.
Some mention Baltic states as progress, because russians come and buy there since it is cheaper. But if it really helped so much, why did you lose so much of your population because of immigration to EU, is life hard but you have option to get away? Is your economy not working? At least you have cheaper products because yours were not protected by your politicians and had to close down because they can not compete?

It seems that one more part of society who are driven by hatred is supported by the civilized and superior leaders of the world to who we should look up to. I wonder when will they start directing their hatred on Russians/Ukrainians who do not support their views?

Also, because of immigration in EU how much time do you have before the radical parts of your societies collide inside your home countries?

Divide and conquer.
