He went to the Temple and he upset the business there. they were selling doves and making people pay for baths, etc.
There is one thing you should never do and that's fuck with a churches or religions money making schemes. It's all about the money.
What happened after that was debatable. Did the Jews give him up as a sacrifice, did they want rid of him or was he just in the wrong place at the wrong time. did he even want to be a martyr?
The Romans killed him, the Jews would of stoned him to death, I think that was the punishment for heresy. The Christians burned people, the Romans fed them to the lions. The Christians were too fucking boring they did not run fast enough.
Fuck with any churches money making schemes and you will get fucked back.
