Day 1 of convincing people that Doflamingo is innocent
All of this is Riku Dynasty propaganda so that they could usurp power from a fair and honest ruler. Doflamingo saw through the evil of the World Government and resigned from the Warlords to distance himself from such evil. The World Government retaliated by sending one of their warlords, Trafalgar Law to convince Luffy to bring down Doflamingo and his ethical operations. The only reason you might think Doflamingo is evil is because history is decided by the winners.
