Was Danny Rand ever so...
emotional and easily manipulated in the comics? He runs away without a word, didn't complete his training, acts like a petulant child, spouts off about his secret order whenever he gets the chance to, and has no reasonable mind. It's like an 11 year (or whatever his age was when his plane crashed) trapped in an adult body. They sure failed when they choose him as the Iron Fist (or it choose him) that's for sure.
Ep11: "I am the Iron Fist. Protector of K'un-Lun. Sworn enemy of the Hand."
-Didn't complete training so he isn't a true Iron Fist more like Half-A-Fist.
-Abandoned K'un-Lun by running away and not really intent on going back so is not a protector.
-Didn't kill any or very very few of the Hand members so he cannot be a real enemy if all he did was just mess them up a bit.
