As it currently stands, this question is too much within the context of personal opinion and isn't supported enough by content from the film. If the OP can reform the question to validate/explain the existence of "the psychological battle" and how/why there could be an actual outcome to the battle, I think it'd stand a higher chance of being answered and not closed.
