Well you say he is soul-less, he is cold and does appear emotionless, but he was fuelled with enough anger and jealousy to murder Liam. He does have some intense emotion, like when he smashed up the factory, it's just normally suppressed and controlled, in this aspect he's similar to Carla, who is also trapped inside. He is detached and cannot handle things when they don't go his way!
And yes the dress sense is good, as the accent and his whole being.And yes his behaviour isn't personal- detachment?? We know little about his background, except he suppots celtic and his ex said he wwas controlling and would 'chew carla up and spit her out' Bit of a tony fan!
