logic

it's easier to plan a defence against a threat that is rational 

because you understand it 

it's more difficult to plan a defence against an irrational threat 

because you don't understand it 

that's why it's difficult for righteous 

to plan a defence against unrighteous 

because righteous often don't understand unrighteous 

unrighteous wants to abuse others 

in order to weaken others 

to strengthen themselves
