[LotR] What did the normalish followers of Sauron expect life to be like if he was victorious? The Easterlings seem like they are pretty normal fighting men. I'd suspect magic on the mind, or they are super gullible if they think Sauron would let them live normally.

Dictatorships are great if you're the dictator.

Sauron is the embodiment of order in all its negative aspects- oppressive, uncaring, crushing. So likely they're like everyone who serves brutal hierarchies and they ideologies that lead to them. They believe that they'll be entering a society that purges outsiders, that puts Good Normal People at the top and finally puts the strange Outsiders with the strange ideas at the bottom. A society of purpose and order, where everyone is in their place.

Naturally, they'll assume they'll be insiders. In this new hierarchal society, they assume they'll be at the top. Likely, a lot of them would be wrong. But they would be far from the first people surprised who the Supreme Leader chooses for the first purge.
