Maybe Drew is following Christ and forgiving. That doesn’t mean forgetting and embracing the guy. But it does release your heart from hatred.

In some circumstances hatred becomes a virtue.
In this case, Carey can only forgive the murderer for the pain and suffering the murderer caused Carey. Carey cannot "forgive" the murderer for the murder because it did not happen to him. Only the victim herself or, of course, God can forgive the murderer for his crime.
But simply "forgiving" is not enough (although can clearly help the "forgiver"). The "process of forgiveness" also requires that the offender must admit what they did and must acknowledge the harm it has done to others and they must ask for forgiveness. Of course, the offender must then repent and be held accountable even if forgiven.
