What kind of bs is that? I'm right now in chapter 1 almost at the end and so far one of the chicks dialogue was along the lines from the post. I mean sure, that logic is correct in the real world, but in the shoes of the sub teacher not knowing what's he's getting into - Why the heck he didn't even try to talk his way out of the hit job? There's already plenty of undeniable proof the shit is real: a mysterious chick wearing classy clothing shows up in what seems like an expensive car shows up of nowhere and starts off the conversation from last night's meeting, meets at an karaoke bar and was told the other guy he's been singing gay songs with is going to be his partner in the hit job, then was told the target info, given new cell phones, was told not to use real name but aliases, see's several millions of Yen discarded at the table. Com'on is his sanity and common sense that low? He's a teacher for crying out loud. How can anyone be that stupid? If he fears for his life for putting an end to the meeting, he might still be left off the hook if he preaches about the contradiction of being evil to end evil will just replace the very same evil they're trying to remove,- the chick might very listen and let him live if he sworn himself to their secrecy. Normally someone like her won't of let him live regardless, but seeing how she goes around getting fools/noobs without using her monetary resources to first get background info of possible hitmans and seemingly to let anyone join; that sub teacher can very well be left alone. What kind of fool let's himself taken advantage of like that? He should be old enough to understand all business exchange is done with a mix of lies, truths, and untold info to sweeten all deals when it comes to brokering deals for huge profit.
All things considered, the sub teacher should of known he's not the kind of person to be a hitman, especially when he rescued the morons he calls his student and lectures them about the importance of life ( 1 of his students nearly fell out the window).
