Witch hunts were largely a Northern European/Protestant phenomenon. The article doesn't say this explicitly, but in a roundabout way acknowledges this citing examples of how the Church largely saw witchcraft as superstition (which itself is a grave sin if done with full knowledge):
"Superstition of any description is a transgression of the First Commandment: "I am the Lord thy God,-- thou shalt not have strange gods before me. Thou shalt not make to thyself a graven thing, nor the likeness of anything that is in heaven above, or in the earth beneath . . . thou shalt not adore them nor serve them" (Exodus 20:2-5). It is also against the positive law of the Church, which visits the worst kinds of superstitions with severe punishments, and against the natural law inasmuch as it runs counter to the dictates of reason in the matter of man's relations to God. Such objective sinfulness is inherent in all superstitious practices from idolatry down to the vainest of vain observances, of course in very different degrees of gravity. With regard to the subjective guilt attaching to them it must be borne in mind that no sin is mortal unless committed with full knowledge of its grievous wickedness and with full deliberation and consent. Of these essential factors the first is often wanting entirely, and the second is only imperfectly present. The numerous cases in which the event seemed to justify the superstitious practice, and the universality of such incongruous beliefs and performances, though they may not always induce inculpable ignorance, may possibly obscure the knowledge and weaken the will to a point incompatible with mortal sin. As a matter of fact, many superstitions of our own day have been acts of genuine piety at other times, and may be so still in the hearts of simple folk." [1]
Aquinas also devotes question 92 of the Second Part of the Second Part of the Summa to supersition [0]. However, none of this denies the reality of the demonic.
