Deadshot and Batman

When Deadshot is apprehended by the Batman, the villain is unable to kill the hero. And that is because his own daughter asks him not to be the bad guy. Which is great, signaling how important his daughter is. But then we see his dream, in which he actually kills Batman – which is weird.
In the comics, Deadshot cannot kill Batman. Maybe it has something to do with I am the light, the Way. Maybe it’s something else. However, Deadshot is unable to kill the Dark Knight, even if he (somehow) has the upper hand.
And I guess this says something about the character. And this will certainly be addressed in a future movie, in which the bad guy proves to be not so bad after all. And this once again leads me to believe that the Suicide Squad will eventually come to the aid of the heroes.
After all, Deadshot is the actual leader of the Squad.
