Who is the the most influential character in Macbeth?

It could have been Lady Macbeth

It has been repeatedly told that Macbeth was the most misogynist Shakespearean play, partly because of the implication of evilness lain in the women involved, partly because of the indecise character of Lady Macbeth, proven weak afterwards by her insanity and consequent untimely death. Although Freud tried to analyze Lady Macbeth’s behaviour on the grounds of an incomplete womanhood due to her childlessness, her movement along the original text seems somehow to lack consistency, the very few hints at her humanity being, from my personal point of view, insufficient to raise such a level of guilt. At first Lady Macbeth even seems superior to her husband, who, although proven courageous in battle, depicts a cowardly lack of determination. Moreover, she seems to be the one who assumes the role of the leader, whereas her husband only submits to her homicidal requests, more or less against his own will, taking the unflattering part of an agent of the woman’s dark desires. Starting as a full member of Shakespeare’s gallery of great feminine characters, seemingly filling in the missing part of the “villainesse”, Lady Macbeth gradually loses importance (within the plot) and mental sanity, to the point of a death suggested as undignifying. Her downfall parallels Macbeth’s ascension towards a status of a tragic hero who made the fatal mistake. In some sense, her destiny mirrors Katherina’s, the shrew – she is “tamed”, reduced, silenced by a playwright who can be conveniently interpreted as a misogynist from this point of view.
