Hi I have an almost 4 yr old boy who when he can not get his own way will hit me, punch at me or even kick me.

When I ask him to stop his aggressive or rough play towards his 1 year old twin siblings he does not listen to me . I have to move towards him and he then runs off.
He has started this behaviour at kinder, snatching from other children, hitting them, pulling them off play equipment, not listening to instructions.
He seems to know what he is doing is wrong and it hurts others but he just does not seem to care. When spoken to about his behavior he says all the right things, i'm sorry, it was wrong to do that, i won't do it again, but within 5 minutes he is.
I have tried to talk to him about his feelings such as when he feels angry, scared etc and what to do rather than what he is, but nothing seems to work.
He yells at me when I talk to him about stopping what he is doing (or when i try to redirect him) or totally ignores me. He seems some what aggressive and destructive when playing alone outside sometimes and I ask him why and he tells me cause Ben 10 does that. He does not watch ben 10 and I am at a loss of what to do next. He used to be such a gentle loving child who never hit/ hurt anyone and listened to me.
