Yes, the EU should consist of democratic and non-corrupt nations, with being a healthy democracy as the bare minimum requirement. You mentioned corruption in Ukraine as if its level were similar to that in other EU countries, but it isn’t. From my perspective, Ukraine’s Euromaidan was a significant step in the right direction, albeit just one of many needed.

The European Union already has nations grappling with issues related to the rule of law and democracy. The goal should be to promote these values and expect them from both current member nations and aspiring candidates. To be considered a part of the European Union, countries should embody these values.

I wish Ukraine and Georgia the best, but it’s not unfounded for people to point out the challenges these states face in those aspects.
