What is the biggest difference between Jews and Christians?

What is the biggest difference between Jews and Christians? Jews and Christians both believe in Jesus. Christianity came from Judaism. The bible came from the Torah. But still Jews and Christians don't get along. Why well i stated that Messiah was one of the reasons Jews and Christians don't get along. But its not just a little reason. Its the biggest reason, and the biggest difference between the two religions. For around 2000 years the Jews have been fighting over the fact that Jesus is or is not the Messiah. In the Jews opinion Jesus is not Messiah for many reason. But Christians view Jesus as the Messiah for many of their own reasons. So who's right? Nobody knows it's only opinions and in my opinion it's not right to hate somebody for their religious opinion. I found a website that might help people who want to know the reasons that Jews don't think Jesus is the Messiah or why Christians do.
