Really just the smartest man in our world's history, with religion aside and beliefs cast out, Jesus was a man with the original indeniable push to "Utopia". He spent his time sharing things to inspire people, to change people's minds about how to treat others. He wanted to make human beings a caring, and for lack of a better reference, a family. Jesus shouldn't have been killed for what he did, but he was because of the same way a lot of people are treated wrong today. The second somebody either disagrees or doesn't understand what somebody else is trying to do/say, they jump at the oppurtunity to thrash at their very existence.
Jesus taught us how to live, taught us how to care, how to love...but nobody listened
