Jesus Christ

Jesus was certainly influential, but you have to admit that his impact was not always positive. I would definitely say the Christianity in Europe was overwhelmingly characterized by corruption, and the bible was one of the most expensive books until Johann Gutenberg invented the printing press. In fact, science and philosophy evolved as almost a counterculture movement during the enlightenment period and so on. Christianity hindered progression, and I therefore find Jesus deserves 1 star.
