It's interesting to see Kitami do something kind for a selfish reason, because honestly does it matter what the intent was if the outcome results in no one really hurt?
He's kind of a shitty person to only apologize to save his place in his friend group, but we have the benefit of seeing his true feelings. If this little interaction hints that he only tried to save Tojo for his own ego, okay? He's not nearly as bad as the people who actively hurt her, who are still bad people unable to redeem themselves. Maladaptive social conformity isn't a crime.
