Don't pat Geoff on the back for this, it was a very contrived and 4th wall leaning remark to once more paint Batman as the asshole Johns imagines him to be due to glossing interpretation.
Bruce was bawling his eyes out when Superman was thought dead and would never make a callous remark about the death of friend or family given his fucking origins.
This was as bad as when Bruce was inexplicably up Hal's ass during Sinestro Corps War, just so Hal could have an excuse to punch him in front of everyone.>Inb4 you're just a mad Batfan
No and Bruce is an asshole, but not for the manufactured reasons fans of other characters make up. There's tons of dirt to use to paint Bruce as the paranoid, duplicitous neurotic he allows himself to be, but a lot of writers lean on the laziest, in-fighting and meta-horseshit where he's clearly just a stand-in for whatever hopped up fanboy they ran into on a forum or because of working in DC steaming over seeing him put on priority over others.
