Prior to 2014, there was ample cordial attitude towards the Russian government and the people of Russia from many in Ukraine.Perhaps. Then again, perhaps Ukraine and Russia can re-establish cordial relations after this war too. Predictions are difficult to make, particularly about the future.
In 2014 Ukraine as a whole decided that they did not want to continue with the way things had been.
This was an opportunity for Russia to stand back, let it happen and show the world that Russia could behave itself. Had Russia done this, they would still be raking in huge profits from sales of oil and gas to Europe, Ukraine would never have put into a position to be eager to join NATO and there would be next to zero threat against Russia from any other country.
The 2014 theft of Crimea and the meddling in the Donbass turned many in Ukraine (but not all by any means) against Russia.
The actions by Russia in 2022 (especially the treatment of civilians on both sides of the line of contact) has turned opinions drastically. Probably better than 95% of those that were not anti-Russian in 2021 are anti-Russian now. And the percentage of Ukrainians that are now extremely anti-Russian has probably gone from a small minority to a large segment (possibly a majority).
The next opportunity for cordial relations between Ukraine and Russia will probably only start after Russia changes out its government for one that is willing to admit the crimes of the Putin government and apologize to the applicable neighboring countries. Given the lack of any movement by Russia in the direction of renouncing its imperialism, I doubt that this is likely to happen while anyone currently an adult in Ukraine is still living.
