How Is Macbeth Responsible For Killing Duncan

Our king, Duncan, has just been murdered and I need to find out who did such a deed. Let's gather the facts here, I am in Macbeth’s castle in Scotland. The witnesses are Macbeth, Lady Macbeth, Malcolm, Donalbain, the two guards and the porter. Macbeth has just told us that he has killed the two guards after seeing that they have bloody daggers and clothes. I believe that someone is trying to frame the guards for killing Duncan. Macbeth is freaking out and he keeps telling us that he can’t live without his king. I still have my suspicions though, because he is the host of the king and he was here all night. My other suspects are Malcolm and Donalbain. Even though they are King Duncan’s sons they are indeed the successors to the throne and they
Let’s begin with the Thane of Cawdor, Macbeth. He had decided to host King Duncan for a night and I know that Duncan agreed. I don’t think Lady Macbeth is involved because she is a woman and could never have pulled off such a horrible thing. I can’t suspect the guards because they don’t have a motive for killing Duncan; they are being fed, paid and given shelter. Macbeth has obviously been here all night and probably didn’t leave his castle. Macbeth is low in the line for being king and after seeing him rise form Thane of Glamis to Cawdor I don’t underestimate his ambition to gain more power, “He bade me, from him, (King Duncan) call thee Thane of Cawdor.”(1.3.110) Having Duncan over at Macbeth’s castle would be a perfect opportunity to kill him because no one would expect anything. Macbeth is a loyal soldier who has served and looked up to Duncan. Macbeth could have easily drugged the guards, snuck into Duncan’s chamber while the guards were sleeping and killed Duncan. He would then
They arrived here at Macbeth’s castle this morning asking if their father was awake. This is when Macbeth goes upstairs to check on Duncan and kills the guards after suspecting them of killing Duncan. I suspect these two boys together because they are the successors of the throne and together they could accomplish this deed. They might have felt like they needed to speed up the process of being king and decided to kill their father. Another thing I noticed about Malcolm and Donalbain was that after they realized their father was dead they didn’t seem to be as distraught as I anticipated. I also overheard them talking about fleeing Scotland which seems a little suspicious, “To Ireland I. Our separated fortune Shall keep us both the safer.” (2.4.163-164) The two of them fleeing is suspicious because they didn’t stay for long after their father died and I feel like they might be trying to hide. I now have to take all my observations into account and figure out who I think killed my
