In the story Macbeth seemed like a genuine nice man and conciderate of others. But, he did seem to have a problem with Malcolm becoming prince and next in line for becoming king. When Macbeth went home his wife tried to convince him that he had to kill Duncan so that he could have a better chance at becoming king and then Malcolm had fled. Lady Macbeth came up with this plan and at first Macbeth was uncertain and didnt want to do it but Lady macbeth said he wasnt a man and that if she was she would kill him. So then he turned around and went along with his wifes plan and his attitude and personality began to change. Lady Macbeth was able to talk her husband into committing murder by basically calling him a punk. So i belive that human nature is determined by what you do and makes who you are. People can pressure you into doing things but it is your decision on wether you go through with it or not. Humans do know wrong from right and there shouldnt be an excuse on why the wrong was done. Alot of what humans do reflects on other individuals and then makes them feel like they need to follow what they do to fit in. It then changes these individuals to act out making a reputation wether its good or bad upon themselves. So therefore their human nature instincts make you who you are.
