He walked in his home-town, Nazareth, all his life, never traveled. And people made his small town into a mall, so he got angry and tilted tables and whipped people in this temple. But, I mean, he never was an murderer I think, so why`d he be sentenced to death on a cross? Was he sentenced to death by the Romans just for being popular? I find it a little strange the story, he obiviously cared about people, so why`d he do anything to them? The society at the time, had pretty much the same rules as now, laws, they couldn`t sentence him to death for nothing
I have only just come across this thread, so I apologise for the late reply. First, I would say that it is important to get the facts correct. He didn't walk "in his home-town, Nazareth, all his life" - we read of Him going into Samaria:
“But He needed to go through Samaria. So He came to a city of Samaria which is called Sychar, near the plot of ground that Jacob gave to his son Joseph.” (Joh 4:4-5 NKJV)
Also, we are told that He left Nazareth, and lived for a time in Capernaum:
“And leaving Nazareth, He came and dwelt in Capernaum, which is by the sea, in the regions of Zebulun and Naphtali,” (Mt 4:13 NKJV)
The incident in the temple took place in Jerusalem, not Nazareth. There was no temple in Nazareth:
“So they came to Jerusalem. Then Jesus went into the temple and began to drive out those who bought and sold in the temple, and overturned the tables of the money changers and the seats of those who sold doves. And He would not allow anyone to carry wares through the temple. Then He taught, saying to them, "Is it not written, ‘My house shall be called a house of prayer for all nations’? But you have made it a ‘den of thieves.’"” (Mr 11:15-17 NKJV)
We are also told why the Jewish leaders wanted Him crucified:
“And the scribes and chief priests heard it and sought how they might destroy Him; for
they feared Him, because all the people were astonished at His teaching.” (Mr 11:18 NKJV)
“Therefore, when they had gathered together, Pilate said to them, "Whom do you want me to release to you? Barabbas, or Jesus who is called Christ?" For he knew that they had handed Him over
because of envy.” (Mt 27:17-18 NKJV)
So they feared Him and they were envious of Him.
You are right when you say that "they couldn`t sentence him to death for nothing." But they wanted Him dead, so they listened to false witnesses who told lies about Jesus:
“Now the chief priests, the elders, and all the council sought
false testimony against Jesus to put Him to death, but found none. Even though many false witnesses came forward, they found none. But at last two false witnesses came forward and said, "This [fellow] said, ‘I am able to destroy the temple of God and to build it in three days.’"” (Mt 26:59-61 NKJV)
Mark's account says that the testimony of the false witnesses did not even agree!:
“Then some rose up and bore false witness against Him, saying, "We heard Him say, ‘I will destroy this temple made with hands, and within three days I will build another made without hands.’" But not even then did their testimony agree.” (Mr 14:57-59 NKJV)
I think at least part of the reason why you find the story strange is that you have many of the facts wrong. (I'm not criticising you, so please don't take offence.)
