I sometimes wonder if Macbeth actually expects his actions to yield fruitful consequences. I also ponder on the question whether Macbeth wants to become King more than he cares about reigning king. After considering the play, I found it to be true that he changes his mind. Macbeth cared about “trammeling up the consequence” but he also promulgates “to be thus (King) is nothing,” He says this only after he perceives things beginning to go awry. In the beginning he only cared about becoming King and explored his wandering cogitations: instances where he sheds light on the fact that he doesn’t have much confidence in his future, and also having too much desire for the crown to be allayed. “We still have judgement here.” “That we but teach bloody instructions which being taught, return to plague the inventor.” and “Vaulting ambition, which o’erleaps itself and falls on the other.” The third one strikes me the most, as he is recognizing that his ambition his risen way too high (vaulting ambition) and that such an instance yields futile results, such as a rider trying to mount a horse but tumbling off after jumping too hard. After he becomes King his situation coalesces into a nightmare of a reality. It’s now not good enough to merely become King; he wants to remain king and at any cost however bloody or treacherous. As he leaps on the mare of kingship, he may brush up against the horse’s mane, but he ultimately springs up too forcefully to stay on for the ride.
