Because he knew it was a possibility. And what, he'd let himself get killed? Bruce had tried, and had died for his troubles. "...I assure you I will not allow for something like that to happen again. I won't.

And I will not put a single finger on Kaldur'ahm. I told Arthur you could be in the room if needed, I just want to tell him exactly what I just told you."
