What I don't like about Jesus is specifically his bent on casting people into eternal darkness, into a furnace, and all the eternal punishment stuff he spoke of. I would otherwise consider him a fine teacher, but a good character is not motivated by fear of punishment.
As for the Bible, there is slavery, misogyny, genocide, murder, torture, death for this, execution for that, liars are called righteous, the innocent are frequently punished, children and slaves are forced to undergo non-consensual body modifications, and god makes extremely cruel demands of people (such as telling a father to sacrifice his son - which is not only very cruel on god's part but also child abuse and attempted murder on Abraham's part).
