Take responsibility.
Like hell he wouldn't. He didn't need that sort of advice coming from the one girl who he had banked his hopes on. Only to be denied the salvation that he sought. The one girl who could even get to save his mission was not the one he was going to listen to for responsibility taking.
All his life, in a bid to be acknowledged by his Father, The Elder, he had known one thing. And that was that, he was going to take responsibility for everything he did.
Every damned thing he did.
because no matter what it was that he did, it was a great feat to show it to his Father, that he was not he weakling he thought him to be. This was that chance to do something similar.
And heaven be damned if he did not take responsibility.
