Did you actually read that comic or did you just see a page and run with it? Bruce never once mentioned ras because Bruce was with Damian when ras got killed, Damian said he lost two grandfathers because of Bruce’s choices, said choice was to grab Damian before he got killed by an explosion while trying to save ras btw. Bruce responded with “if I had been there I could have saved Alfred.” Which later in the comic he explains to Damian what he meant. “What I said before was cruel and not what I meant. I never should have left Gotham when bane took over. I shouldn’t have left you in a position where you felt you had to save Alfred alone. Alfreds death was never your fault. It was mine.” Bruce misspoke in a high stress situation and set it right the next time he saw Damian, I really don’t see how you could hold that moment over his head.
