[Dr Strange] Why didn't the monster torture Dr Strange?

At the end, the monster repeatedly kills him relatively quickly and painlessly, so it seems like Strange is a hero because he's more willing to deal with the tedium. But would his plan have worked (that is, would he have gone through with it as readily) if the monster had basically put him in hell for days each time he came back?

We didn't see every iteration of their battle during the montage. Dormammu probably killed him in every way conceivable and a few more before giving up. It's just like in Groundhog day where we only see a fraction of of the days he spent stuck in the town while people have calculated that the whole movie takes place over several thousand years.
