Miller evidently knew there was a good chance that TSUN may try to kick him to the curve at some point in Softie's career. Why else would you save years' worth of texts, facebook posts, etc.? He was making sure if they ever screwed him over he had the evidence to take them down. Then that fateful day happened when Bucky accused him of being a woman beater trying to get ahead of the story and he said, "Aight, Imma see who gets the last laugh in all this" and the rest is history. I guess he had seen their past actions where when you outlived your usefulness to the plantation they disposed of you and pretended like you never existed. He made sure he had the goods to come back from the dead and haunt the plantation. Good for him.
