The want to punch someone in the face is not (always) tied to maturity.
Back in high school, I set up a few circumstances so as to be ("legitimately") able to hit someone in particular in the face. This dude tried to rape the dearest person to my heart, and I would've punched so many times I would have been brought to my trial like Hannibal Lecter. What this dude did to that person brought up something in me that my mind was desperately trying to keep away from myself.

Go to the source of why you want to punch this person, and you'll know yourself (a little) better.
