The romans enslaved, killed and conquered a lot of places, with a lot of different religions and cultures. But eventually we see most of them accepting roman language and culture. And this lead the romans to treat them 'well'.
Why did the jewish keep resisting the romans when other didn't?
A lot of it has to do with the monolithic, monotheistic religion of the Jews compared to most of the other areas under Roman rule.
The Romans had a very open idea of religion. They figured, the more gods, the better; who's to say Thoth won't protect you in Egypt, but Epona in Britain? It's a little unreasonable to expect Roman gods to follow Roman people all over the earth, I mean, they're busy enough as it is...
Also, they encouraged their people to worship the Emperor as a god, the embodiment of Jupiter on earth. Mostly they didn't mind if people held to their own beliefs, as long as they paid lip service to the new ones too (lots of gods, remember). To the Jews, though, this was Not Ok.
They believed in only one God. To worship any other was sacrilege. And as their previous government was heavily involved with religion, this was perceived as an even heavier burden than it would have been already- just another way the Romans show you who's in charge. It was intolerable.
