eren will definitely be able to control the power eventually. and his dad gave it to him for a good reason. he said "everyones fate rests on him being able to control this power" my theory is that the royal family could have stoped the titans with this power whenever they wanted to, but they enjoy the control. they want humanity caged up in these walls. they didnt plan on other titan ppl to come kicking the walls down. maybe the titan ppl thought the royal army would finally act and but when they didnt erens dad took the power for himself. but its just my own little theory
