Not a lot of things are black and white. But this is one of them. Theres nobody except Russia here to blame.
In 90s and yearly 2000s Russia was invading Russia and tens of thousands of military and civilians died.
Do you have a source for this?.
I was wrong a bit, the number includes Russian volunteer fighters and with covert Russian military is estimated to be about 14400.
