Does this "what you ask for I was born" mean "what you ask for(request). I was born..." or "what you ask, for(because) I was born..."? The usage of "for" is confusing.

ex) King Louis had been taken from his throne and imprisoned. His young son, the prince, was taken by those sho dethroned the king. They thought that inasmuch as the king’s son was heir to the throne, if they could destroy him morally, he would never realize the great and grand destiny that life had bestowed upon him. Finally ager intensive temptation, they questioned him. Why had he not submitted himself to these things-why had he not partaken?
These things would provided pleasure, satisfy his lusts, and were desirable; they were all his.
The boy said“ I cannot do what you ask for I was born to be a king”
Prince Louis held that paradigm of himself so tightly that nothing could shake him.
