Kagari was diagnosed a latent criminal by age 5 and chimped out at her so he actually was a bad egg and totally deserved what he got.
By the by past this first Psycho-Pass it turns to shit.
About Makishima, he's only bad because he's above the system. If he weren't he'd not have misbehaved so much. It's objectively not his fault. Even if it were she obviously hates the Sybil system but going without it means overall more lawlessness, so it is the lesser of two evils. That's the point.
Also, if Makishima and other asymptomatic criminals are such mavericks then they really are technically better than normalfaggots. Notice how they never call them sociopaths? They're a step in evolution. The queen bee. That's the point. We are a hive, humans are, without a real queen bee. Government is a joke, so we wish for a god, possibly an AI god, but that's like wishing for the philosopher's stone. Instead you get a new breed of men, that's the asymptomatic mavericks that are above the law and you. They think higher than you, they are above you, judge you, you dn't get to judge your god(s).
If you were a good judge you'd not make it about x person. It's not about her, not about kou, not about any x person, not even about Makishima as he can be used to stop crime over all, of which pisses Akane off but she logically knows he's for the greater good.
On season two, that over 700 'I want to paint it black' fucker is so faggy. He doens't act like someone with the highest crime coefficient. By three the whole show is different too without getting into why.
so just stop watching
