No, and frankly I always thought the notion 'forgiveness is strength' is Christian brainwashing with the aim of the elites exerting control over justice-- with the happy byproduct it makes for good statecraft, and generally yields a more happy populace overall. By that I mean it is greatly inconvenient to peace to have the plebs running around exacting revenge. Vengeance inevitably escalates, and ensnares ever more people. Doesn't take long before your in a land of warlords waging perpetual war. Better to teach people that there is some sort of divine grace in forgiving those who grievously transgress against them.
Either way, the State can't tolerate individuals arbitrating their own sense of justice. So it also makes the bitter pill of having the shape of justice dictated to the aggrieved easier to swallow; perhaps the kernel of truth to the cliche that letting go of anger keeps it from eating one up from the inside. Because one is impotent to act on that anger against the might of the State. After all, history doesn't seem so rich with royals-- including the Christian kind-- who forgave those whom murdered their loved ones when they were in a position of martial supremacy.
But I suppose this is just a cynical outlook.
