No, you never arm nazis. Azov is worse than just a "right wing militia", they are actual blood and soil neo nazis. How many times that this have to backfire backfire before people realise arming Nazis is a terrible idea?

Also this ignores the fact that far right elements were essential in the 2014 coup taking place in Ukraine. The support of Nazi groups was needed to seperate Russia and Ukraine diplomatically. That's the whole reason "the West" has been arming and supporting them for close to a decade now.
