The 'Jesus' of the NT is a manipulative psycho. Now that doesn't mean the real Jesus or Yeshua ben Yoseph was a psycho, probably a very good practicing Jew of the Essene sect, a pacifist who cared for people.
Love your enemies.
Do unto others as you would have them do unto you.
Love God and love one another are the most important commandments.
Mercy over sacrifice.
Forgive everyone, as often as they ask or need you to.
Bless your enemies.
Give to those who ask of you.
Give to the poor, feed the hungry, care for the widows and orphans.
The least among you will be the greatest - you lead by serving.
God sent his son, not to condemn the world, but to save it.
He laid down his life for his friends.
He denounced hypocrisy where he saw it, and taught what should be done instead - through word and example. (Those I love, I rebuke... remember?)
Now I get that the above is not what you're taking issue with, (although you dismiss Christ because he didn't give credit to the sages, even though He was around before those sages had ever been born... and even if you don't believe that, then certainly God was around beforehand. So it wasn't as if the Sages came up with it on their own either. And Christ did say that he did only as His Father had taught him. Designs, wouldn't the sages have rather seen the glory go to God than themselves?)
Your second issue is with hell, right? So lets talk about the 'unquenchable fire'. First, it could be judgment, it could be refining, even during life (and the jews you have been speaking for, since not all factions believe the same, do believe in a sort of purgatory/refining period after death, depending on how bad they were during life), and it could also be annihilation. Even at its worst, it is the 'fire' that is unquenchable. Eternal. Not the person (or the chaff) being thrown into it.
So compare what man has made of this doctrine and how we might still be influenced by their interpretations, to the rest of Christ's example. Consider also the story about the adulterous woman about to be stoned. After none cast the first stone, (since none of them had the right to), neither did Christ condemn her... even though He was the only one with the authority to do so.
