I think that there are some fundamental conflicts that are inevitable. Parris' and Proctor's conflict is fairly unavoidable. Both hold a fundamentally different world view than the other one. Proctor sees religious expression in a more personal light, while Parris sees it as one where there has to be a social affirmation of the institutional hierarchy, something that Proctor is against. When Proctor speaks of Parris' desire for gold candleholders and how he could never sit and look at the center of the church in the same way again, it reflects a conflict waiting to happen. The Putnam family and the Nurse family also feature a conflict that is brooding. The Putnams resented the fact that a while back, one of theirs did not receive favor for a prestigious church position and someone representing the Nurse family did. As it says in the stage directions for Act I, this is something that Putnam bore in his heart and would not relent. At the same time, with the land charters being revoked in Salem, there was a general fear of land possession, a desire to strengthen the hold one had in order to have more. In this light, Putnam, one of the major land holders in Salem was bound to run into conflict with another, something that Giles Corey brings out in his accusations against Putnam in Act III. Another reason that the Putnam family would have borne inevitable resentment towards others, in particular Rebecca Nurse, was in their experience in child birth. Ann Putnam's dead children in contrasted with the "success" that Rebecca Nurse featured was a source of brooding resentment to which end some anger towards someone was going to be released.
