Why personal choice has a greater impact on the characters in the play of Shakespear?

In Shakespeare's plays, there is evidence to prove that the characters themselves affect their lives with (wrong) choices that they make. This can be seen in Macbeth's example - a man led by his ultimate ambition who makes wrong decisions and tragically dies.

Explanation:

One of the main themes explored in Shakespeare's plays is fate vs. free will (personal choice). Many critics are interested in finding out whether the characters directly affect the outcomes of certain situations with their choices, or everything depends on fate.

This conflict is particularly present in the tragedies - in Macbeth, for instance, we might wonder whether Macbeth has certain power to change his life, or, in other scenario, everything is preordained through the presence of the supernatural (the witches). There is, however, more evidence to prove that Macbeth is not just a victim of his fate. Macbeth is a victim of his desire to become a king, which is why he makes multiple wrong decisions and suffers the consequences of them. Macbeth could have changed his mind and stopped with his plan  - instead, he proceeded with the plan even when he had guilty conscience about the first murder he committed. This means that he had a choice, but made a wrong one.

If we consider this example, it is evident that personal choice has a greater impact on the characters in the play - that is, that their downfall is not preordained, but is a consequence of their wrong choices.
