Venom - Darkest Realm

The main theme of Allegro burst into the living room like an angry fury, from the look of which the blood freezes in my veins. For the vast majority of people, this would not be called “music” at all, because they would not receive either joy or pleasure upon hearing this. And the second part did not bode comfort and consolation: she sang about mortal torment, about hopeless longing for what was lost, about futile searches for truth ... In Scherzo - again desperate throwings and feverish appeals to the merciless sky: how long?! .. And what is the intended outcome ?. The outcome turned out to be sad: the theme of the finale, like a beaten bird, tried to fly up and down, but every time it returned to the beginning, and dusk, darkness and despair were gathering around ... And suddenly on the last pages everything changed instantly, the hopeless minor turned into a peppy major,the drowsiness was crossed out with joyful passages ... What does this mean and how is this possible? ..
