Of course you coud still hate him but pretend to love him by oathing to him.
I do fear however he is working on a way to read our minds and so we can only have a "certain period of time" to lie when we oath. If we oath with hate the mindreading device will sound the alarm and well you can guess where we go thereafter.
But that's a bit down the road.
It will be a new frabjously joyful world. Trust me. I wouldn't lie to you. Everyone will do/say everything they should. Life will be perfect for everyone who complies. Elsewise those who don't will be sent to another place from which they will never return so they don't infect the Paradise Utopia. An ecstatic exotic exciting place to live under the benevolent guiding hand of don.
