What were some positive and negative outcomes of the French Revolution?

I think the negative outcomes were mainly short-term and the
positive ones long term. 

There is no question that the French
Revolution was needed. The Ancien Régime was brutal, denying basic human rights to the vast
majority of subjects. There was no freedom of speech or religion and the nobility could act with
impunity with no repercussions for such acts as raping female peasants or assaulting or abusing
members of the lower classes. The Roman Catholic Church had also been corrupted by its alliance
with the throne, with important posts reserved for members of the nobility rather than people
with the best qualifications, such as piety or theological knowledge. As Brettd pointed out, much
of the tax revenue, often taken from the poor and middle classes, was squandered on luxuries for
the court rather than the common good. Creating a fairer and more democratic society was a strong
and obvious positive.

The actual way in which the Revolution was
conducted, though, was harsh and brutal. The Reign of Terror (5 September 1793 – 28 July 1794)
was particularly brutal. Just as it is wrong to mistreat someone because they do not come from an
aristocratic lineage, it is equally immoral to mistreat people because they do come from an
aristocratic background. The ideal of liberty could not be realized until all people began to be
dealt with equally as individuals, not as members of classes. The eventual outcome, though, of
the current free democratic society is a strong positive.
