Most Jews do not believe in any coming messiah. The messiah was never contemplated as being a god anyway, the notion is entirely inconsistent with Judaism.
The Mashiach/The Messiah the idea of the Messiah according to the Torah
"The mashiach will be a great political leader descended by a pure male line from King David (Jeremiah 23,5). The mashiach is often referred to as "mashiach ben David" (The Mashiach, son of David). He will be well-versed in Jewish law, and observant of its commandments (Isaiah 11,2-5). He will be a charismatic leader, inspiring others to follow his example. He will be a great military figure who will win battles for Israel, freeing the Jews of foreign domination and establishing a Torah-based kingdom in Israel. He will be a great judge, who makes righteous decisions (Jeremiah 33,15). But above all, he will be a fully normal human being, not a god, demi-god, or other supernatural being.
When did Jews stop offering sacrifices, and why?
For the most part, the practice of sacrifice stopped in the year 70 C.E., when the Roman army destroyed the Temple in Jerusalem, the place where sacrifices were offered. The practice was briefly resumed during the Jewish War of 132-135 C.E., but was ended permanently after that war was lost. There were also a few communities that continued sacrifices for a while after that time.
We stopped offering sacrifices because we do not have a proper place to offer them. The Torah specifically commands us not to offer sacrifices wherever we feel like it; we are only permitted to offer sacrifices in the place that God has chosen for that purpose (Deuteronomy 12,13-14). It would be a sin to offer sacrifices in any other place.
The last place appointed by God for this purpose was the Temple in Jerusalem; but the Temple has been destroyed, and a mosque has been erected in the place where it stood. Until we observant Jews recapture the Temple Mount and rebuild the Temple, we cannot offer sacrifices.
Orthodox Jews believe that when the Mashiach comes, sacrifices will be renewed. Some of us think it better not to wait for him, but to be about the business of rebuilding the Temple and reinstituting the sacrifices; in any event, it is permitted to bring all of the regular order of sacrifices today on the Temple Mount at the place where the altar was, even now when the Temple is no longer standing.
Do Jews want to resume sacrifices?
Orthodox Jews do. There are several places in our daily prayer services where we pray for the restoration of the Temple and the resumption of its rituals, including the rituals of sacrifice".
Your description of Judaism, I hope, is essentially your own and not all encompassing. I deduce from it that it is" all things to all men" changing constantly, without rules. The Jews had difficulty in obeying God and were cast out because of this. One cannot claim to be a Christian unless the laws of the Scriptures are adhered to. The lawless will be as many as the sands of the seas, in the last days. Billions................. so you wont be alone.
