Ukraine isnt even a democarcy now .
I will agree that it is an extremely borderline case, and could be argued not to be a democracy. But it was moving in the right direction, which had Putin scared. If Ukraine becomes a democracy, with western style prosperity, then Russia can too. If Russia can too, then Putin is over.

If Ukraine can end that cultural corruption, then Putin is done for. Putin desperately needs Ukraine to fail.
