The dagger scene in Macbeth is the turning point where Macbeth goes from a "heavenly" person and transitions to become the evil person that will go to hell. The witches show him dagger and what he could do with it.
Macbeth is obsessed with the thought of earthly power, being the king and ruling over the people. This is his vision of heaven, when in reality, he is doing the opposite, he is creating a hell on earth for the people.
Towards the end of the play, all the other characters believe that Macbeth is going to go to hell. Young Siward says, "No; though thou call'st thyself a hotter name / Than any is in hell" (5.7.6-7). Then Macbeth tells him his name, and Young Siward says "The devil himself could not pronounce a title / More hateful to mine ear," and Macbeth answers, "No, nor more fearful" (5.7.8-9). Thus Macbeth claims to be more frightening that the devil himself.
Witches are traditionally associated with hell and evil. The three witches in the play give Macbeth the evil prophecies which start Macbeth's evil doings such as murdering multiple people. These actions prevent him from going into heaven.
The three witches at the beginning seem to Macbeth to be beneficial, and good with their prophecies. However, they end up revealing their intentions to be evil, for Scotland and its inhabitants.
In the beginning of the play, Macbeth has multiple lengthy arguments with himself over whether he should go ahead with the murder that would surely land him in hell but would grant him power on earth. Or would he give up his opportunity for power (king) on earth and go to heaven?
Throughout the play, there is a contrast between the Macbeth and Macduff. Macbeth is the evil one and is going to go to hell for his actions while Macduff is honourable and loyal throughout the play, he is more of a person that would go to heaven in the aspect of the story.

Macbeth is tempted to murder the king so that he could be the king and have a better life for himself. Just like how Adam and Eve were tempted in the Bible, the outcome of his actions were not good.
