Rudiger is only helping Dulio because they both share the same wish (the reason why Dulio wants to win) and that wish is this: To stop children from being born with Sacred Gears that will affect them negatively like what happened to Rudiger's only son who died and many other children dying from possessing a Sacred Gear. Rudiger sees Dulio as the best Angel in his eyes, for what he did for his son and holds a great deal of respect for him, which was visit his son because his son saw Dulio as a Hero and Dulio made him happy with what life he had left.
