What is the moral of Macbeth act 1?

I studied macbeth this term at school and the whole focus was on how shakespeare's plays are universal and everyone can relate to them, accross time, race and . Shakespeare displays elements of human nature throughout his plays especially Macbeth which makes it easy for us to relate to because we all have these traits within us, just to different degrees.. The whole concept of Macbeth is that the character, Macbeth is a "tragic hero" he starts off noble and 'good' and well liked and then forces beyond him (being witches) play upon his character flaw being ambition and give him false hopes which ultimately turned him evil, even tho in the end he only had himself to blame..Banque is also exposed to this but does not bring upon his downfall because it was not his character flaw like it aws Macbeths. Macbeths character flaws were ambition, power and deception. he was obsessed with power and was decieved by the witches and his wife that he would become king. banqoes character flaw was deception as he trusted that macbeth would not kill him even tho he suspected he was up to something. from what i remember act one was about the witches targetting macbeth and planning his downfall. they preyed upon his fatal flaw being ambition and that is where macbeths life began to spiral down. not sure if this is waht you mean but i hope i helped.
