Obi Wan warns Luke i think it is either in the novelization for star wars or the radio drama, that misuse of the force can lead to the dark side.
I think the problem is the more you use the force to cheat the more addictive it gets. But asking a jedi not to use the force would be like asking one of us to cease breathing.
I think the whole Jedi Credo is to teach proper use of the force and restraint. Whereas the sith would say the strongest rules and that justifies the ends.
