I dunno, it just feels that thoughts of the consequences never cross his mind. I guess, this time it's sorta justified (although, killing a guardian deity and not expecting something to go wrong?).
Honestly, i just can't seem to put a finger on the whole thing - "teachers" force him to perform like a goody two-shoes, he's not buying that and tries to cheat the system in the most blatant ways possible, and then gets genuinely surprised that he has to repeat.
