No
Just about nobody is loyal to Macbeth at the end. Seyton (sounds like Satan and who knows? it might be him) is one of the last to stay with Macbeth.
They are poor and need money, and are loyal to Macbeth. And he degrades their manhood.
Seyton was loyal to Macbeth right to the very end.
Macbeth does this in the play Macbeth
Macbeth's army is loyal to him out of fear and intimidation, while Malcolm's army is loyal to him out of respect and loyalty to his rightful claim to the throne. Additionally, Macbeth's army is fueled by ambition and desire for power, whereas Malcolm's army fights for justice and to restore order in the kingdom.
In the play Macbeth, Malcolm portrays himself as a potential sinful tyrant in order to to test Macbeth. Malcolm wanted to see just how loyal Macbeth would be.
Banquo in Macbeth is depicted as honorable, loyal, and cautious. He is a trusted friend of Macbeth, but also a wise and moral character who suspects foul play in Macbeth's rise to power. Banquo's sense of integrity and skepticism ultimately lead to his demise at the hands of Macbeth.
Macbeth was a loyal vassal of King Duncan. Macbeth's act should not be considered regicide.
The Witches forecast the downfall of Macbeth and then vanish. (not killed by anyone)
Banquo probably doen't know for sure about how Macbeth is planning on killing Duncan so he can become king. Even if Banquo did know, he is a very loyal friend to Macbeth and will keep all of his suspicions to himself. Which is ironic, because Mabeth ends up hiring murderers to kill Banquo, which goes to show you that Macbeth really isn't that loyal.
At the start of the play, before meeting the witches, Macbeth is still loyal to Duncan. The forces of Norway and the rebel Macdonwald (whom he kills in battle) could be considered his adversaries at this point in the play. After he meets the witches and begins to entertain thoughts of regicide, anyone who stands between him and power becomes his adversary (Duncan, Malcolm, Banquo, Macduff...) One could probably make an argument as to why Lady Macbeth might be considered Macbeth's adversary as well.
Macbeth fought several battles for King Duncan, including combating a rebellion led by Macdonwald and the invading Norwegian army. Overall, Macbeth is depicted as a brave and loyal warrior in the play.
