The dream was: become Shanshah E Hind one day
As he has not Corrupted his mind with silly education this single dream gave him all the motivations to take action in that direction.
When his opponents due to their faulty education and lack of any significant dream face him they just shiver.
While he just win due to his superior mission and lack of any “hindering back educational philosophies” of morality, honesty, mercy, Adherence of rules etc
