Yes ! I also hope the story has a happy ending, but I think it does and that Raul will follow the path of redemption once he's done with his last targets, and rebuild a better world by forgiving his former enemies with a new benevolence
Maybe even in the end he'll be defeated by the Gods and they'll forgive him and let him live, and that Raul will then understand that he no longer needs to take revenge leading him to understand and change, that is what i think
