Anthony Ray Hinton's story is heartbreaking, horrific, and frustrating. This shows how inhumane the death penalty is and the fact that the criminal justice system is broken, which makes it hard to guarantee that only actually violent criminals are executed.
I'm not religious and I'm not necessarily for forgiving people who've wronged me, as Hinton is, but I can see how forgiveness and his religious beliefs were important for him during his time in prison and to help him move on with his life.
