Ok, so just cause they are geneticaly engeneered and Belong to military we should get bunch of sociopath who doesn't cook, aren't geeks, covert perverts and hero fanboys?
They are young, trying enjoy what they can and deal with own problems which is far more than most mecha pilots were ever able (They are too busy with angsting).
They act as normal teenagers so I threat them like ones. So does many characters in show.
