Generally the recommendation is always to go for the commission straight away. For someone going for a commission and a pilot slot enlisting comes with its own problems and drawbacks that more often are not overcome by the "advantages". That being said, some time in basic training getting yelled at may actually help this kid.
Then again, the entitlement attitude is something that is deep and strong. Coupled with obvious anger problems and the inability to have a civil conversation, I'm not sure basic training could break that. Especially now with the new basic training and the cell phones, "stress cards", and "MTLs are not allowed to <insert military training here>" attitude.
The only serious advice I can give you is check your attitude at the door and remember that you haven't even completed the first step (College) on this journey and act accordingly. Its a long hard road full of hard work, dedication, and thick skin. If you can't put in the hard work, or even more importantly if you don't want to put in the hard work.... save us some time and yourself some headache and quit now.
