I am really trying to not say negative stuff about christianity, but you asked.
In jewish history there have been jews that rebelled against judaism.
During Moses' time there was Korach. Korach challenged the leadership of Moses and Aaron, and him and his followers were destroyed.
Just like in any religion or group there are ones that do bad things.
Based on Judaism, if Paul and the others, focus was on jesus, and not the one G-D of Israel, then he did a really bad thing according to what G-D said in the Torah.
I think that christians are staunch supporters of Israel is great. I mean that truely.
If christians believe that you must "accept" and believe in jesus to go to heaven, then aren't all jews going to hell according to christian beliefs? Heck, I don't really care that much. It's a free country, and everyone can believe whatever they want.
That's because your NT history isn't based on understanding judaism. You are saying what the jews believed, when christians don't have an understanding of what jews believed.
This is what I believe, even though I am guessing, I believe jesus and his minions at that time had a hatred toward jews, because the jews weren't buying what he was selling.
You asked a question about the death penalty in an earlier post that I didnt' get too. Sorry.
Although the Torah gives the death penalty, the criteria for carrying it out is so high, that it made it almost impossible to enforce.
I am lazy so I am going to copy and paste this.
The Death Penalty in Jewish Tradition - My Jewish Learning
According to the Mishnah (Sanhedrin 1:4)
the death penalty could only be inflicted, after trial, by a Sanhedrin composed of twenty-three judges and there were four types of death penalty (Sanhedrin 7:1): stoning, burning, slaying (by the sword), and strangling. A bare reading of these and the other accounts in the tractate would seem to suggest a vast proliferation of the death penalty. Yet, throughout the Talmudic literature, this whole subject is viewed with unease, so much so that according to the rules stated in that literature the death penalty could hardly ever have been imposed.
For instance,
it is ruled that two witnesses are required to testify not only that they witnessed the act for which the criminal has been charged but that they had warned him beforehand that if he carried out the act he would be executed, and he had to accept the warning, stating his willingness to commit the act despite his awareness of its consequences. The criminal's own confession is not accepted as evidence. Moreover, circumstantial evidence is not admitted.
From Practice to Theory
It has to be appreciated, however, that practically all this material comes from a time when the right to impose the death penalty had been taken away from the Jewish courts by the Roman authorities. According to one report in the Talmud (Sanhedrin 41a) the power of the Jewish courts to the death penalty ceased around the year 30 BCE; according to another report (Sanhedrin 52b) it could only have been imposed while the Temple stood and must have come to an end not later than 70 CE when the Temple was destroyed.
This means that, although earlier traditions may be present in the Mishnaic formulations, the whole topic, including the restrictions, is treated in the Mishnah and the Talmud in a purely theoretical way. It is hard to believe that when the courts did impose the death penalty they could only do so when the conditions above obtained. Who would commit a murder in the presence of two witnesses when these had solemnly warned him that if he persisted they would testify against him to have him executed for his crime?
That the Mishnaic material is purely on the theoretical level can be seen from the oft-quoted statement (Mishnah Makkot 1:10):
"A Sanhedrin that puts a man to death once in seven years is called destructive. Rabbi Eliezer ben Azariah says: even once in seventy years. Rabbi Akiba and Rabbi Tarfon say: had we been in the Sanhedrin none would ever have been put to death. Rabban Simeon ben Gamaliel says: they would have multiplied shedders of blood in Israel."
This Mishnah is a kind of reflection on the whole law of capital punishment. Faced with the clear biblical injunctions, the Rabbis mentioned could not simply have said that capital punishment was wrong. After all, the Bible states that it is right and has to be imposed on the guilty. But the statement seems to imply that the Rabbis welcomed the development by which the Sanhedrin no longer functioned with the power to impose the death penalty and Rabbi Akiba and Rabbi Tarfon speculate that even when the Sanhedrin did possess this power, various legal means could have been adopted to negate the imposition of the penalty.
