Hi, why are you talking about killing Banquo, killing people for your own good, is not what you should do. Killing people is the opposite of peace which is not what anyone would want. Killing the king to become the king is treason. Doing illegal things for your own good, will eventually lead to something very bad happening to you. Killing someone is bad enough but getting a whole army to help you continue killing people, is a very bad thing to do. Just think about it, killing a king to rule Scotland, that is not right, and if you ever kill Banquo, would it be something to be proud about? The inner devil of you by killing one person after the other will start increasing, and eventually, all your problems will be solved, by murdering someone. You have to change yourself before you start become an evil person, killing someone day by day.
