YMMV / Monk S1E11 "Mr. Monk and the Red-Headed Stranger"

• Magnificent Bitch: Wendy Mass is a friendly, seemingly blind woman and the true murderer of Sonny Cross. Having lost her parents and vision in a car crash caused by Cross decades ago, upon having her vision partially restored, Mass sought revenge. Tricking Cross into meeting her in an alleyway, Mass shoots him in a way that's impossible for a blind person. When country singer Willie Nelson unexpectedly arrives, Mass quickly frames him for the murder by acting as a witness, continuing to fake her blindness to ensure nobody suspects her. When Monk reveals the truth behind the case, Mass thanks him for uncovering it, having been wrought with guilt for framing an innocent man. When Stottlemeyer suggests making a deal with the District Attorney, Mass asks that her only leniency be a window in her cell so that she can make the most of her newly regained sight.
• Unintentionally Unsympathetic: Mrs. Mass killed Jason "Sonny" Cross and falsely implicated Willie Nelson for the crime. It's also established that her motive was getting even with Sonny because he killed her parents in a DUI crash in the 1980s and got a light sentence for it. Where the trope comes into play is that Mrs. Mass's actions were worse than anything Sonny Cross did. It is clear that Cross's actions were stupid, irresponsible and criminal, and the outcome of his actions was a tragedy, but he didn't intentionally go out and murder anyone. (However, it's heavily implied that he didn't regret his actions one bit and was an all-around jerk, given his history of embezzling.) Mrs. Mass, on the other hand, committed premeditated murder and then blamed an innocent man (and perhaps even would have allowed him to be convicted) for her crime, despite feeling guilty for it and being glad when Monk ultimately catches her. That's not justice. That's a crime in its own right. However, Stottlemeyer suggests that the "extenuating circumstances" could help her chances in court and the general company feels sympathetic to her request of serving her sentence in a private, windowed cell.
