Archie, like Emile Janza is a person with no friends. Though friendship is not especially common for the boys in The Chocolate War, Archie and Janza are two characters who seem similarly peculiar in their attitudes regarding friendship. They play roles at the school to earn respect, but never attempt to earn any affection.
At the end of chapter 15, Archie considers Janza and thinks he is both "crude and gross", yet Archie is "fascinated". These ruminations serve to show Archie's disdain and dislike for Emile Janza. However, Archie goes on to articulate his world-view which seems to connect the two characters:
The world was made up of two kinds of people - those who were victims and those who were victimized.
Archie's point of view, as expressed here, demonstrates a somewhat complicated view of Janza. Archie feels that he is not like Janza, not crude, not violent, but he fits in the same general category. They both choose to be victimizers and this is part of the role they adopt to earn respect, instead of making friends.
