Komamura Sajin’s Fire
Komamura is like an Old Testament prophet or judge. He burns with the desire to punish, to crush the evildoers. He does not hold back.
I understood that back then, when he just learnt of Aizen’s treason, he was ready to crush Tousen as well, he would not hesitate or hold back.
So it is like he told Zaraki – “You concentrate on the opponent’s outer strength and ignore the inner source”. He knows he is not that good with the outside strength, not that skilled. But his inner fire is second to nobody, and when it comes to that – the clash of raw power, raw will, who crushes whom – he does not lose.
I think he thinks the old man Yamamoto is the true prophet (note that this guy’s element is also fire), and that Yamamoto knows the will of Heaven, true justice, which Komamura will unquestioningly obey, even if it is incomprehensible (again, he’s very old testament in this – he says like Abraham: “if he says it is just, then even death is just”. he decides to trust). So when he says he is indeed like an insect, he means his relationship to Yamamoto – in comparison with him, he is just a small insignificant helper in bringing heavenly justice to the world.
[again, we have the principle of pairing similar opponents. Poww worships his king like a God. Why does he lose? Basically, Poww is simple. He just does whatever is told; worships because he is overwhelmed by power. Whereas Komamura thought about it at some point and consciously resolved to follow Yamamoto without question from then on]
Contrast between Tousen and Komamura is very interesting. They must differ in their concept of justice and with cognitive strategies to deal with uncertainty (though perhaps Tousen also resolved to trust – but Aizen, not Yamamoto). But we know a bit too little about Komamura.
But there is also the difference of attitude. Both want to uphold justice. For Tousen, this means protecting lives and peace. So when he kills people, he does it as a NECESSARY means. He would prefer to terrify them, to let them know fear and this way learn that what they do is wrong; teach them to avoid fight (this is what his Bankai is about). Note how Tousen and Ichimaru complement each other – Ichimaru and his squad represent the very horror and despair of war (Tousen could say: “if it is not me – justice and peace – then it is Ichimaru. Do you want to live with this guy, to live in his dark world?”). Ichimaru is Tousen’s shadow.
To go back. Tousen does not have the desire to punish as such, he does not hate evildoers. He is kind. But for Komamura, crushing the evil ones IS a part of justice for which he burns. He burns with holy anger.
