Forgiveness requires genuine repentance. The idea that Erika "forgives" an (almost certainly) unrepentant killer doesn't make any sense. It's baffling to me how many Christians (or at least people who wear that label) don't understand this basic principle of Christianity.

God offers forgiveness for all of us, but in order to be forgiven we have to admit we've done wrong and do our best to change that behavior. The killer has done neither.
