A good start is to give your character a motivation, or even better an obsession to build him around, maybe even multiple.

For example, Du'un was once a relatively powerful but typical Sorcerer, he desired knowledge and as a result he still up until this day has that tendancy (though it has faded by now.)

Then, he quickly learned that it took a super-human amount of will to survive and become head will (spoilers) of the entity/communion that is the Abyss (yes, I have a reason for it, while it may be canon-breaking as to how it came to be, once I reveal all it will not be as canon breaking as you think.) As a result he became obsessed with self control, which gives you his up until now very calm and not even cruel exterior for a Chaos Sorcerer.

Then came recently when he realised that he could no longer rely on his self control (the final click was the fight with Vulture) and he realised that he now has to start relying on other things other than his will to win, as a result his calm composure remains but is beginning to be filled with cracks of madness.
