Normal people, they believe in the teachings of Jesus and God. Like normal people they can be jerks or nice. Christians have been portrayed for the most part as a bunch of science-ignorant homophobics, and yes this is true for many people, it is not the case with every single Christian out there. Anywho, they're normal people, believe in a dead guy's teachings and like normal people screw up time to time.
Some examples of good deads from Christians are Alcoholics Anonymous, orphanages, charities, and hospitals. Some examples of them screwing up include the Spanish Conquisition, the Crusades, and the West-Boro Baptist Church.
