This was good stuff, but I don't honestly think he would feel such anguish over Crota's death. My reasoning is oryx's belief that if you were destined to be all powerful, you would survive (the whole universe in its purest form thing)....and Crota proved to be too weak in his slaying. He also threw him to the Vex with no thought, essentially telling Crota to dominate or die. Regardless, I like it. Good job.
