Leo's world plummeted into utter desolation, sadness, madness and feeling the pain of betrayal every day. The feeling of loneliness suffocated him, he can not bear to see his adoptive father and Violet looking happy every day while he was suffering unbearable pain. There was something sinister inside him that was wanting to get out of his system. It's the feeling of wanting to appease his anger, to bring punishment to the people who inflicted so much pain on him. He wants to end the torture that he was feeling inside, he wants to be free from the horror of everything that he's been through, he can no longer take it anymore! He wanted to wipe the smile on their pretty faces...he wanted to see them suffer and pay a hundred times of what they had done to him.
He wants to kill them slowly...painfully and savagely...until all his anger can finally be sated and that's the only thing that can free him from the pain and agony that he was suffering all this time.
