Everybody thought that the killer was angry and just randomly kicked that box in the bus and dropped his shit there. I thought he did it on purpose. He bailed on the killing because things didn't go according to plan. Even if he killed Kayo right then and there, he couldn't set up his scapegoat (Yuuki) this time since Satoru ruined his first attempt.

I interpreted that as a "Fuck you, I'll be back".
That sounds strange. If he was so analytical and free of passion, why would he be killing in the first place? It's not like he'd be murdering the abused daughter of random addicts for some higher political reason. If the target is offered to him on a gold platter right after he failed to snatch her after going through more trouble, I'd find it unlikely he wouldn't seize the opportunity.
