Do the witches in macbeth play a central or collateral role in shifting the ambitions and actions of the plays characters

Macbeth's demise was due to fate - I would choose character and say that  every point that Macbeth had choose to do something terribble so then had , he received some kind of sign telling him to go back but of course he dosent listen to  it. The witches had pumoed  him up and told  him that he would have been  destined to rule over Scotland.  they play a collateral role you cant blame them for macbeths since, but they still sorta kind did help him push down the path of terriblenes 

Well based on the summary,   the setting plays a big role in char. development since the cat has been spoiled and babied her whole life she has to figure out how to survive on there own for the first time. and since winter is coming the cat is faced with lots of dangers and troubles. but, like you said with the storm that brought an invasion of rats, since she is   a cat shell figure out how to kill and get food and the storm is the best way to learn right. can you mark me brainliest pls! read more on -
