Happy Papy Minecraft

It's been years since he changed from his dark ways and started helping others instead, but still no one has forgiven him. He hasn't been able to forgive himself either. He finds himself in a dark place, having no way to end it. But then, a few visitors give him the idea and determination to go back, and fix, EVERYTHING. Even if that means he will never return. The question is, is it possible for the guy to be forgiven for his actions? If he tries hard enough, can he forgive himself?
