Verified Answer :

He was mostly to blame for a few reasons. First, by standards even of
that time, the powers of the monarchy in Great Britain were very high.
The parliament could pass anything unanimously, and it could be
immediately vetoed by the king, under any circumstance.

He had the power to create his own laws, too.

The
primary reason why the Colonists viewed him as a tyrant, was because he
imposed several taxes and tariffs upon them that, by their standards,
seemed extremely high. Surprisingly, these taxes only accounted for 1%
of the colonists' income.

However, the thing that we note Mr.
George the Third for the most, is the fact that he did not listen to the
Colonies' petitions and letters.

I acknowledge that in his
personal life, King George the III was a good husband and father, and a
very moral man. However, his position on the colonies marked him forever
as a tyrant, and an example on how we should not let a lot of power get
into the hands of one person.

All of the power people have can some times go to their heads!
