That last target felt a bit rushed, despite being presented as the most dangerous of the lot. All the mind games and counter moves felt like they amounted to nothing in the story.
Even the cop completely gave up, just giving a final (and useless) warning before leaving the scene.
At least, it's an ending without loose ends, but it feels like some elements were left unused.

If I remember well, him and his friends wanted to use the "juvenile immunity" law to commit the worst crime they could think of, just to have fun experiencing both the crime and the protection of the law after that. The victim's identity didn't matter, it's not like they specifically target the MC's sister.
That's psychopath-level insanity, but it's not unheard of in real people.
