Considering all this, we may say that there are some standards that giallo directors try to keep from film to film, but the main standard is "the hunter and the prey". In giallo movies might not be any foreign protagonists, but there's always a murderer, who kills or plans to and his victims. And those are the core images of a woman and a man. According to giallo canon, the victim is always a pretty girl or a woman, and though some men might also suffer from a killer, this will always be the addition to the main murders. In giallo films the murder is traditionally shown from the killer's point of view: we see a screaming woman, getting wounded, blood, and the hands of a maniac in black gloves. This refers to Laura Malvey's concept of the male gaze. According to her theory, a viewer has to follow the camera's point of view, which means that if we see a murder with the maniac's eyes we reinforce our perception of a woman as prey. Talking about eroticised murder, as it is shown in giallo, we may also agree with Malvey that directors tend to sexualise women to respond the masculine voyeurism. As for the core depiction of a man –- it is in the image of a murderer. We don't know who is the killer, their gender or personality, the only thing we see is an image –- tall dark figure in leather gloves and often black coat. Witnesses of a crime in giallo movies often describe the murderer as "a man" though they never can be sure about it, as they don't see the face.
However, in giallo movies, the depiction of a woman and a man is more profound. It often occurs that under the murderer's mask hides a woman, usually close to the prime suspect. The motives for the crime might be different. Sometimes, a woman becomes a murderer because she had suffered from a man (which is often sexual abuse and often in childhood), sometimes because of mental illness. There are often situations when a prime suspect was the main victim of a woman murderer. There's always mutual cruelty –- that's what giallo movies tell us. They do it in a very peculiar way: by aestheticization of this cruelty.
