I found myself loving him because of his purity, the character is a total crystallization, there's nothing but passion toward black in him and his lethal thirst of chaos keeps him clear from hypocrisy. The guy just doesn't turn a blind eye to how important is presence of Batman because he knows that would make his game "so boring".
His stories of his 'round-the-mouth cuts are in a way so that they make you feel his rage is all brought up by past events while in fact its obliging of his chaos desire, he wants to become black as he knows the world is all about black and white and other things are defined according to these two, pure pleasure is in being God or Satan, is to have no one upper hand, is to looking at the world that looks the way you want it to look like.
His laughters after receiving pain seems actual not to make the enemy outraged but as enjoying heavens of pain, like a vampire that smells sweet scent of blood while portraying its crimson beauty.
Not all of it maybe, maybe its all because I do believe in hidden joys of agony and mourning.
In the drunkenness of solitude I fear no more the solemn realm of death
No single sigh from my lips as I drink the wine of bitterness
My heart is aching nevermore for I know that all may end
Just I and the poetry of the night now forever one.
