No. They were legally Ukrainian but Russian speakers, ethnically Russian.
The protesters in Kiev were primarily ethnically Ukrainian and they wanted closer ties with the EU but the government didn't want that. Ukrainian Russians wanted closer ties with Russia and so naturally resented the protests.
The government probably understood that if it wanted to prevent ethnic conflict, it made sence to maintain the status quo.
Presumably student protesters couldn't understand that and so conflict ensued. Then Western politicians intervened. Russia started giving warnings to the West to back off. The West didn't, and so Russia checkmated us. And now we're bitter.
Russia was still wrong in what it had done. I'm just saying that we provoked it and so have to accept at least some of the blame ourselves.
from Wikipedia:
One of the first issues the parliament approached was that of the language, annulling a bill that provided for Russian to be used as a second official government language in regions with large Russian-speaking populations.
[97] The parliament adopted a
bill to repeal the 2012
law on minority languages, which protected the status of languages other than Ukrainian. The proposal alienated many in the Russian-speaking regions of Ukraine and
[98] a few days later, on 1 March, acting President
Oleksandr Turchynov vetoed the bill, effectively stopping its
enactment.
[99]
In the meantime, on the morning of 27 February,
Berkut special police units from Crimea and other regions of Ukraine, which had been dissolved on 25 February, seized checkpoints on the
Isthmus of Perekop and
Chonhar peninsula.
[11][12] According to Ukrainian MP
Hennadiy Moskal, former chief of the Crimean police, these Berkut had
armoured personnel carriers,
grenade launchers,
assault rifles, machine guns, and other weapons.
[12] Since then, they have controlled all land traffic between Crimea and continental Ukraine.

To some degree, Ukrain itself had provoked Russia by trying to suppress its ethnic Russian population. Russia was still wrong, but I'm just pointing out the extenuating circumstances.
