To quote the Joker (not P5's Joker, mind you) "Everyone is awful these days." On a side note, in the fanfiction Persona 5: Rebellion where Sae is in charge of taking care of the MC during his probation, she frequently abused him by imposing strict rules on him, openly stating how much she wants him back in juvie in his face, threatens to send him back there and even points a loaded gun at him for hanging out with Makoto.
They persecuted and ostracized the main character for a crime he didn't commit, the woman he saved threw him under the bus to save his own neck and likely only recanted her testimony because it was finally convenient for her to, Ryuji Sakamoto's so-called friends turned on him over his conflict with Kamoshida that led their team to disband, caring only about themselves and willingly bending over for an abusive teacher for the sake of their careers, several foster families abused Futaba Sakura and blamed her for her mothers death, Sae Nijima deliberately condemned innocent convicts with forged evidence and God knows what else. The 99% blindly supported Shidou, in spite of him confessing his crimes, refusing to think for themselves, "necessitating" the Phantom Thieves to mass brainwash them by stealing their collective Treasure.
