Hi. I am having a little trouble understanding your post. If my answer doesn’t make sense, I apologize. We don’t view Jesus as a demon. There is very little in Jewish scriptures that can even be seen as referring to Jesus (as we view our bible. Obvioiusly christians find many references to Jesus in the Torah) and the few paragraphs in the Talmud that may be referring to Jesus are not kind to him. If they were written about Jesus they were written at a time when Christainity was threatening the future of Judaism. So I would not be surprised at the bitterness.
Also, because the Talmud was originally oral, the student had a lot to memorize. So it was common to use exaggeration where appropriate, to help the student remember.
Regarding the Talmud, I am not aware of any passage in the Torah that teaches us to steal from non-jews. One of the major concerns of the Talmud is fariness in business. It recognizes that if we can cheat each other in business, we can do much worse to each other. In general, the rules in dealing fairly with non-jews are very strong. It would violate everything that normative Judaism stands for to teach that we can steal from a nonjew.
Having said that, I am aware that the Talmud contains opinions of many, many rabbis and some of them had less love for non-jews then others. It is possible that the Talmud may have recorded an opinion that is hateful to a nonjew, but when using the Talmud to understand what our legal rights and obligations are, it clearly is interpeted to teach that we are not permitted to steal or otherwiswe cheat a jew or a non-jew.
