Here is a pretty good description from an EW article of Lex Luthor from the Batman v Superman movie that helps explain his character and motivations. I think its a paraphrase from Jesse Eisenberg:

Have a like, I enjoy YJ as well.

It wasn't as bad as some parts of the internet make it.

"Unfocused" is an apt way to put it, particularly in the second half. They also Spider-man 3'd it. That's not to say it's as bad overall as Spider-man 3 but it has the same basic problem.

Also someone should've told Eisenberg he was supposed to be playing Lex Luthor, not imitating Ledger's Joker.

Affleck was probably the best part as Batman and should get the chance to do a more substantial Batman movie.

I haven't seen the movie, but based on the reception of this past film and the way the last few DC films have gone, this would seem to be relevant.

Well, I grew up with Batman from BTAS and he didn't kill. Affleck's Batman has no qualms about it though.

It's a bit hard to really solidify Batfleck's view on his moral code, since we only get glimpses of his past and his stand on justice and criminality, but the way I view it is that this version of Bruce is someone who is a very tired individual, and considering how psychologically damaged person he is and the stage that it has left him through the years, and now that he is facing the threat of meta-humans and further changing the world around him, it has pushed him to the very extreme. Bruce's primary motivation for the Batman persona has been the ability to create fear, and I find it vital that fear has to evolve for him and how he faces the individuals he interacts with through the years, as well as his view on morality.

One can argue a lot of different forms of ethical discourse focus specifically on justice and the way it correlates with death, but with Batfleck I believe he has strengthened his viewpoint on justice, and has come to the realization that justice is blind. His comments in the movie about comparing criminals to weed, the actions that Superman has committed, and his monologue to Superman about his upbringing--that violence and fear is the answer--his stance on justice is so strong that the removal of whatever threat he deems necessary to combat, and in turn be able to give everyone the equal right to the most basic liberties, which will benefit most the least advantaged person in society, in his eyes justifies the death of those threatening others--whether it be a common criminal or a meta-human.

Of course it is hard to pinpoint exactly when he took this stance, since it could have been earlier in his career, and thus killing people is almost a common thing for him, but I hope it gets reflected upon in future movies.

I don't mind Batman killing. I think too much has been made of his reluctance in the past. It worked in those cases, but change is not a bad thing, so long as he doesn't turn into the Punisher.

I don't mind Injustice Superman.

Why not? Superman can be tricked by the Joker into killing Lois Lane and her unborn son.
This leads to Superman killing the Joker, imposing martial law and training his own army.
This version would also kill Lex Luthor.

Why not make Superman go mad with power.


Then the first Justice League film would be about taking on Superman and his army.
Besides, The Justice League doesn't really need Superman as a good guy.



That would be a terrible idea. But hey that is what Zack Snider will do.
That vision that Batman had is the direction the series will be going in.



So hope you like what Snider will do.


After the Justice League have taken down Superman and his army, that will be it. There will be no more Superman in The Justice League.
The Justice League will be Batman, Wonder Woman, Green Lantern, Cyborg, The Flash, The Arrow and that's it. No Superman.
