Alas… how terrible is wisdom when it brings no profit to the wise, Johnny?
Angel Heart DeNiro Quote
Video: Angel Heart
Louis Cyphre, a homophone for Lucifer, appears in Margaret's living room and tells Angel that despite his attempt to break the contract, he has known his true identity since the beginning. Angel refuses to believe him, insisting that he knows his own identity and will tell Winesap that Cyphre is trying to frame him for murders he himself has committed. Cyphre then reveals that Winesap is also dead, and proceeds to unleash Angel's repressed memories: in a fugue state that Cyphre induced, Angel did indeed murder Fowler, Toots, and the Krusemarks.
Finding himself alone, Angel then flees to his hotel where he finds the police in his bedroom. The body of Epiphany, wearing his dog tags, is in his bed, killed with a gunshot from his pistol stuffed into her vagina. Angel finally accepts the truth of who he really is. The New Orleans police detective tells Angel that he'll burn for his murders, to which he replies "I know". He will be executed for his own daughter's murder, as well as the other killings, and Cyphre can at long last claim what is his - Favorite's immortal soul.
Over the end credits, there is a lengthy sequence of Angel inside an iron Otis elevator cage, which is interminably descending, presumably to hell. (Short clips of this sequence have been seen in Angel's dream sequences throughout the film.) As the screen fades to black, Cyphre can be heard whispering, "Harry" and "Johnny," announcing his dominion over both their [shared] souls.
