Two Face does not toss his coin for opportunities to kill someone. He tosses his coin to make a decision on whether he does actually kill them or not. In this case whether he can kill Bruce. He really wanted to, which is why he kept acting frustrated every time the coin came up no. Secondly the opportunity to kill Bruce was the same. He was right there in front of him fighting his men. Two Face was just sat there in a chair casually watching this and tossing the coin over and over. It's not like different opportunities were popping up.
The scene demonstrates Schumacher had no idea about the psychology of the Two Face character. Two Face is not a blustering character who is constantly jumping around like a hyper clown, laughing at the top of his lungs. He doesn't keep tossing the coin over and over so he can kill someone. He was as campy as Carey's hyper active Riddler. Apparently this was Jones' idea because he didn't want to be upstaged by Carey. There's a reason why he constantly makes worst villain lists. Because he's actually an awful villain. The worst role Jones ever did.
In addition to the comic books, Two Face/Harvey Dent has appeared in Two live-action BATMAN movies: 1989‘s BATMAN and 1997’s BATMAN FOREVER. In the former, actor Billy Dee Williams played Gotham D.A. Harvey Dent, while in the latter, Tommy Lee Jones played the villian Two Face himself.
Fans complained about how "Harvey Two Face" was depicted in BATMAN FOREVER. As portrayed by Jones (see left), he was a cackling, campy, over the top clown, often playing second fiddle to Jim Carey's Riddler.
Also going against the Batman mythos, this Two Face would flip his coin until he got the desired outcome -- rather than allowing chance settle the issue.

As for Batman Forever, it's as camp as a row of tents overall. It's got some serious somber scenes, but they're out numbered by the cheese and camp. Yes that was a decision on WB's behalf after Batman Returns and all the backlash controversy, McDonalds Happy Meal promotion being killed off etc. The two universes feel like polar opposites. That was intentional. It was not meant to look and feel like Burton's because WB felt he'd gone too far with Returns:
*An end to the batlash: Hiring Schumacher to direct the summer-of-'95 release is seen by insiders as an attempt by Warner Bros. to get the Batman movies back on track. The studio, which declined to comment, has always given Burton full credit for reviving and modernizing Batman, and Burton's office confirms he will executive-produce the next film. Still, Warner doesn't want a repeat of the macabre 1992 sequel, Batman Returns, which frightened small children and angered many parents. And even though it earned $163 million in the U.S. and Canada, Returns made substantially less than 1989's Batman, which grossed $251 million. ''Warner Bros. didn't want Tim to direct,'' says a source close to the project. ''He's too dark and odd for them.''

They wanted to get away from Burton's style and tone altogether. You cannot imagine the likes of the nose biting, raw fish eating, baby killing Penguin in Schumacher's happy camp world. The likes of this is not goofy noir, it's pure camp:
The common street thugs were camped up to look brightly colored:
Even the guns had neon in them lol:
The writing's on the wall. That's the level of camp we're talking here. To this day people still ask if Schumacher's movies are supposed to be linked to Burton's because they're apples and oranges.
Schumacher has never come across to me as someone who ever spent a day of his life looking at a Batman comic book, or if he did, then it was the silly comic strips of comedy characters. His knowledge of Batman didn't seem to go beyond the old 60s TV show. And I say that as someone who grew up on and loves that old show. I think someone gave Schumacher some comic books to look at and he just flipped through them and saw lots of color and ran with it. There is just no real understanding of the Batman universe involved in these two films. This always bugged me, even as far back as 1995 when Schumacher was saying these same things in interviews. He made some fun fantasy adventure romps, but they could have been so much more had they actually adhered to the characters more closely. They managed to do alright with this one, though Batman & Robin is where is really fell apart, but overall you can tell that none of them really cared to explore the source material very closely and make something more from it. They were content to take the most vague and basic attributes of the source material such as Batman's parents being murdered, Dick Grayson's circus origin, and Two-Face's duality and just run with it without adding any real depth to it. They especially didn't seem to understand Two-Face at all. He was just a loud, obnoxious, campy goofball who doesn't even obey the basics laws of the coin.
