It always bugged me how in Man of Steel, Superman has to deal with the moral quandary of breaking the bad guy’s neck at the cost of vaporizing a family.
Like they spent the previous 20 minutes punching each other through buildings. No way that was the first family they killed.
I've missed a lot of DC movies, but wasn't Ben Affleck's Batman inspired to come out of retirement due to this ... Or something like that? I might be completely bungling the details.
