Does the Russian Orthodox Church recognize Adolf Hitler as a Saint?

So, I recently found out about how the Main Cathedral of the Armed Forces in Russia maintains a section containing Adolf Hitler's hat and uniform as relics within a wing of its building. Since it's my understanding the Catholic and Orthodox churches only maintain relics of the saints, does that mean that the Russian Orthodox Church recognizes Adolf Hitler as a saint? Can someone go to visit the church to see Hitler's hat and pray for him to pray to God on their behalf? If they don't regard Hitler as a saint, then why do they maintain his relics?
