Arima tests all the ghouls he faces. He is always looking for interesting ghoul as he himself said in JACK. Hide knew it, that's why he asked Kaneki to eat him and regain his energy, that he needed to show to Arima, a dead end for Ken, that he was worthy. That way he could show Arima that he was strong, interesting. And Arima recognized it, with: You are good, Kaneki Ken. So Arima decided to spare him.
