If what he chose ended up being the outcome he wanted, then that was a good ending. However, on the other hand, if it doesn't go his way, then it's a bad ending. Ashnard just thought that if he didn't accept it and the outcome turned out to be what he wanted, then Ashnard would regret it. This is a gamble. Good or bad the outcome he got, once Ashnard had made up his mind, he could no longer back down.
As Ashnard stared at the hand outstretched in front of him, he had probably already faced a thousand battles in his mind. Thinking of all the possibilities if he accepts or rejects it. Ashnard was feeling indecisive right now.
Just like when Servulius gave him an assignment. At that time, he accepted it and there were two results he got. His fear of the prophecy about his friends didn't come true—that's the plus side. However, his relationship with his friends is not what it used to be. It's a sad happy ending.
