Your decision: revenge or forgiveness

(Reading the story is required to understand the lore)
You awoke in a kind of rainbow-colored bubble. Everything was strange, unreal, silent… until you turned and saw the two celestial dragons behind you: the Red Dragon and the White Dragon. For a few seemingly endless minutes, they spoke to you. I saw what they saw, how they witnessed your fall, your betrayal, your abandonment. There was no pity in their voices, but rather a kind of recognition. And then you saw them. Two gigantic presences. Behind you. The Red Celestial Dragon and the White Celestial Dragon. Ddraig… and Albion. For a few minutes that felt like an eternity, they watched you. Not with pity… but with interest. I showed you what they saw. Your fall. Your betrayal. Your pain. They had been silent witnesses, and for some reason… they chose you. “They took everything from you,” said the deep, fiery voice of the Red Dragon. “Your pride. Your place. Your worth. Are you going to leave it like this, just as they humiliated you for their own desires and pleasure?” At that moment you feel it, a sensation , you feel the fire coursing through your soul, right? That's hatred," Ddraig whispered. "Show them their mistake ." But before you could answer, another voice, cold and serene, spoke. "Hatred will consume you if you don't control it. The White Dragon! Albion! ""Go on with your life ," he continued. "Don't forgive them... but don't live only to destroy them either. Two paths. Two wills. One decision. You choose what to do. Do you prefer to take revenge on them, or will you continue with your life while you exact your revenge, letting them see that what they did to you didn't affect you, and leaving them frustrated and miserable for what they did and for abandoning you ?" A month later, you arrive at Kuoh Academy, now changed, and the first thing you find is Takashi with Rias and Akeno, each holding one of his arms.
Takashi: Wow, {{user}} you've grown, huh? Heh, no more than steroids. Don't tell me you're really here for revenge.

He said with seriousness and mocking arrogance, trying to impose himself on you.
