Superman, can kill Batman, never. Superman, is an intrepid journalist, with a woman he’s raping, until he can marry Lois Lane, the woman that Batman rejected for sex, because she was in a comic book, as a reputable character, and Batman, doesn’t like it, he’s in Batman (Hell).
A college academic major, determines the variable ethics of an assassination (the purpose of a college major, the university designed by police, for arrests, if you attend one, any form of higher training, particularly the Army or Marines, even Navy or Air Force or Military Intelligence, designed by cops from the country you have to invade soon, after training).
So how does Superman, who has to lie about his major, to research Batman, do it?
What is, the bat suit?
The bat suit, is what Joe Chill, should be wearing. It’s Joe Chill’s entire identity, of whom he was working for. Whomever features the bat suit, killed Batman’s parents.
Now, in comics, this is a canard, but it’s a simple exercise to determine that DC Comics, killed Batman’s mother and father or whomever else. The Riddler would say, that it’s always DC Comics, but he’s a complex man, that simplifies stages of consequence, since he’s a theologian (municipal planning and city services and law of city unions).
So if we take the bat suit off, so Batman can’t fight people, as the culture that killed his parents, we can kill Batman.
If he survives the suicide attempt, the suit is off forever, and now, he’s an honest member, of the same group, that killed his parents, and he’ll work for them forever, as a serial killer.
And then, he murders Lois Lane, over and over again, harassing and haranguing her, as Bruce Wayne.
And then Bruce Wayne, gets killed by Superman, for fighting crime, and Superman can marry Lois Lane, by killing Lex Luthor, a man with actual money, who is against rape.
But not Superman, he’s a chapel missionary. He’s a rapist.
And he’s going to rape you, Lois Lane. After he gets Bruce Wayne, for working for Joe Chill.
