While it was a mistake, can you blame him?

He watched Kakashi kill Rin, after he made Kakashi promise to protect her. It was his dying wish. Obito entrusted Kakashi with his eye. Not only that, he loved Rin. He also knew Rin loved Kakashi. So Kakashi killing Rin would definitely be a trigger. Also considering his team had two prodigies (Kakashi and Minato), it seems even worse that Rin had to die.
