Your morals are a large part of who you are... you have built them one by one based on your life experiences... thus turning away from your morals... would be akin to turning away from yourself...

This being said.. morals are bound to change over time, a result of experiences that you have yet to live. It is possible in the future that your morals will change... it is called evolution.

Could it be that you are anticipating a "mid-life" crisis?
