I've figured the cycle out

In Vincent's tale it says 'fate comes full circle, and now it's Vinnie boy's round.' My take is that the cycle is: Birth, a troubled past, a mistake, and death at the hands of another. Violet: Abused and beaten, trusted Stevie, and was killed. Jenny: Faced into foster care system, didn't listen to her intuition, and was killed. Screech: Also faced into foster care system, joined a gang and did drugs, killed Jenny, and was killed. Vincent: Struggled with Debt collectors and alcoholism, killed a man, and we'll soon find out if he dies or not. Stevie: Mentioned he was a wrongun so likely to have a bad past, killed Violet (presumably in Prison), and we'll see his fate soon too. Richard is the only one to break this cycle, but we've no idea of a troubled past, but a mistake (killing Screech), maybe he'll die in Starry Night?
