Very hard to say. What kind of Fascism would Korea adopt at this point? And a Democratic Korea starting here would not be the same as the OTL South Korean democracy developed from the right wing dictatorship.What differences would there be between a fascist and a democratic Korea? Both are homogeneous nations.
And we should not just think of this DPRK as a larger version of OTL North Korea. Korea was never divided here, passing from the Japanese colonial rule too the Communist state. Also Kim was evicted from power for a few years, as opposed to an unbroken reign letting him build his personality cult. Also with no Korean War to devastate peninsula economic/infrastructure conditions and demographics will be very different too with Korea's suffering limited to air and naval raids during the Chinese War.
