Describe Khan's personality (ST:ID)

Of course I'm talking about the one from star trek into darkness. His posture, how he acts, how he talks, how he thinks, etc. I need this information for an article i'm doing. Also, how do you think he would act in everyday life? Would he just be quiet like he did in the movie or would he act like he did in sherlock holmes?

Calm, apathetic, savage, perfect posture, he talks normal, it just sounds weird because of his voice. Doesn't make any gestures when talking, which gives him his "stillness". He is completely driven by revenge. He would probably act like a sociopath in everyday life. You know, the quiet type, with little regard for anyones feelings.
