In a bit of a digression, if you want a game which gives you every options possible, regardless of how feasible it is, then you should really try the Conan Chronicles modules.
For example, when you, as a slave, have to do gladiator fights, and are bound to a small complex where all the gladiators live, you can actually still try your luck against the dozens and dozens of guards defending the place.
It does not forcefully railroad you, saying that because there are guards there, you should go by the long hard way of the main quest. There's really nothing stopping you from escaping directly. And what's amazing is that the maker of the module painstakingly has written down the branching plotline of even that situation.
If you want to attack someone, all it takes is right-clicking and choosing Attack on that person. Regardless of whether that person is supposed to be essential to the plot, you can still kill him or her, and go for the super-hard alternative anyway.
