So that's what he decides? To kill an innocent living being, who did so much for the Earth? LOL, while he's good? And as for his fight against crime... It means he drivers around Gotham and murders everyone he doesn't like? Nothing of this demonstrates essential traits of Batman - intelligent, incorruptible, in control. Looking for a purpose - proper character flaw for Bruce Wayne. Finding it in going for an unjustified kill... Snyder's Batman should probably kill himself, because I'm sure there was collateral damage in his 20-year career. And what if he turns bad? With his power and wealth... You know, there's a myriad of ways to make Batman address possibility of Superman turning evil. But the script doesn't allow that. It rather has a lunatic Batman, who can't see, can't hear, can't think, can't talk. Only kill. It's a potentially powerful idea, that was completely mishandled by people, who had no idea how to make it work.
He's good? Who said anything about Batman being good? He's not good. He's sick. As Alfred says earlier in the film, Bruce is consumed by a fever. That fever is not as extreme as murdering everyone Batman doesn't like, since it's clear Batman only uses lethal force in the pursuit of a goal he believes will benefit humanity. He doesn't kill the sex trafficker at the start of the film, for example. Batman, in BvS, is a lunatic. Bruce even admits that he's a criminal who has lost any claim to being a good man because good men make promises they can't keep and no good man stays that way. This Batman is clearly suffering from PTSD, anxiety, and depression.
The script doesn't allow Batman to cope with the existential threat of Superman in a healthy way because the script intends to show a man who has lost his way. It is a film about how powerlessness and fear corrupts, but also how those things can be overcome. It's a film that, at its heart, is about a how a dark and cynical world and one broken man finds redemption. Your need for Batman to adhere to a rigid characterization that does not allow for his humanity (flaws, mental illness, etc.) to be exposed and interrogated is highly problematic, in my view, because it is sterile and limiting.
This is a story that posits that if Bruce intends to be a vigilante -- a hero -- who commits to his crusade because he believes that a sick, broken, and morally bankrupt city like Gotham can be saved, then he must first be able to see that a sick, broken, and morally bankrupt man can be saved. The film offers Batman a chance to bury the Batman that forced the world to make sense by telling himself beautiful lies and by adhering to moral codes only out of fear of losing his fragile psyche to his demons. Rebirth comes from that death because a Bruce who has been to hell and back can genuinely say:
Men are still good. We fight. We kill. We betray one another. But we can rebuild. We can do better. We will. We have to.
If we don't count that unconfirmed death of the garbage truck driver, he doesn't. As for death of ninjas and the poor criminal fella they were going to execute, that's manslaughter at the worst. When Bruce tried to save his life, he didn't go for the kill. When powder was set aflame, ninjas had plenty of time to escape, but they were ordered to stay by the fake Ra.
Excuses the Nolan films and fans of those films use to avoid confronting consequences.
He crossed this line when he dressed up as a bat and started his fight against crime. It's called "vigilantism". Unlawful methods against a city, full of unlawful element. When law can't handle the situation, guys like Batman enter the scene. They try to uphold the spirit of law. But since it means taking law in their hands, Bruce Wayne doesn't cross certain lines. So even intrusive technology was a big deal, because extraordinary situation demanded extraordinary methods. Killing Superman before he turns evil, and there's no evidence he will, isn't an extraordinary situation. It's an insane construction inside Bruce Wayne's head, driven by poor screen-writing.
How does the questionable rationale "extraordinary situation demanded extraordinary methods" not apply equally to these two situations? Crossing "certain lines" is a bogus standard because Batman is the only one drawing those lines for himself. How do you account for the even more extraordinary problem that Superman presents, particularly in light of Bruce's ambiguous vision of the future and the warning he received about the future? Both courses of action cross a line. Both courses of action are entered into with the belief that a line must be crossed in order to protect the greatest number of people. Is there proof that Superman will someday become evil? No, there isn't. But Bruce believes that if he waits until there is evidence, then it's too late. It's enough that he's been warned about the future and has seen the damage Superman causes by merely existing. What Bruce sees isn't a hero whose good acts counterbalance the evil done in his name. He acts like a firefighter who sees the embers of fire that is just starting to burn out of control and decides to execute a controlled burn to stop the fire from spreading. He's a surgeon who removes an organ or amputates a limb before disease or infection becomes a mortal threat. There is some method to his madness.
I assume you admit Bruce Wayne's immoral behavior in BvS. That's a start.
Huh? The film itself admits Bruce is immoral, and I never claimed otherwise.
1) Why did Batman bring Doomsday back into the city from an isolated island in the middle of a river? To make it harder for himself to collect it and plan an attack? Smart move, Bruce.
2) Why does Bruce refuse to listen to Superman? You can spin it whatever you like, you will never be able to justify it. It's like Bruce is in a trance for two years at least. It's not believable by any stretch of imagination.
3) Why doesn't Bruce attempt to talk to Superman instead of throwing threats during their first meet up during the chase? Because filmmakers refused him in an intelligent move.
4) Why making a spear out of the precious kryptonite? There are many ways to utilize it more efficiently. Because otherwise it won't be like in Excalibur. But Batman is acting dumb? No big deal.
... And so on. Don't try to justify it by "because he's in a psycho state of mind".
1) I'm not sure to what you are referring. This is what I remember from the film: "
Why did you bring him back to the city? The port is abandoned. And there's a weapon here that can kill it."
2) Batman doesn't listen to Superman because he is consumed by rage. Intelligent people with very high IQs are not immune to letting their emotions override their reason and judgment. It is foolish to believe otherwise.
3) Talk to him about what?
4) Already been covered, but to reiterate: Bruce made kryptonite gas and created the spear so he could kill Superman with his own hands.
The justification for much of Bruce's behavior is psychological, which is typically the case for most humans. Your refusal to accept that as a justification in favor of the mistaken belief that intelligence is an adequate antidote to mental illness shows an incredible misunderstanding of human behavior and psychology. It means that you hold Batman to standards that are godlike and set him apart from practically every character in fiction since storytelling began.
