Rocky was the real antagonist
Think about it. She targets a blind man's house with the intention of stealing all of his money. Throughout the film she constantly chooses to put her own life and the lives she's with at jeopardy in order to avoid losing the stash.
The blind man, imo, was not very "evil." All the rich girl had to do, in return for taking the life of his daughter, is be a surrogate for nine months. She was fed well and she could return to her normal life after she delivers. Granted get family paid him off, but he clearly doesn't care about the money, otherwise he would have changed his horrible living conditions for the better. The only reason anyone died in this film is because an armed robbery put him in a position in which he had to defend himself.
Another reason why Rocky is the worst is because of how hypocritical she was. After *spoilers* Alex cut her down from the impregnation device ( another point for the blind man bc he doesn't rape), she wanted the police to punish him for what he's done. HOWEVER, in the final scene of the movie she finds out the blind man survived, and she doesn't care because she's already made it out with the money.
Rocky doesn't care about the well-being of her friends OR about justice. All she wanted was a payday so she could live out her fantasy.
