Nihilistic Hero

I was forced to be a hero, but I personally brought about the end of the world. ——Until the system's cold beep told me: [Nihilist belief reaches 100%, activate 'The Coming of Nothingness']. When I opened my eyes again, I was transported back to the day before I killed my loved one. She stood in front of me holding a little boy, her smile still on her face: "Let me introduce, our son is also the key to destroying the world." I looked at the child's empty eyes that were exactly the same as mine, and for the first time I fell into true confusion. The end of heroism is destruction, and the end of nihilism is rebirth. When the world falls apart in absurd reincarnation, Who is the real hero and who is the ultimate destroyer?
