I've written a series on the Jesus myth theory. At best, I don't think we can know much about the historical Jesus since the gospels aren't historically reliable, and Paul doesn't say much about him. What we're dealing with is a literary character, and we need to explain the origin of Christianity.
If you're insinuating, though, that Jesus was loving, so if Jesus represented God, God must be loving too, I'd say that just pushes the implausibility back a step. Now, the dubious point would be that Jesus adequately represents the source of all things, including the inhuman things in the wider universe about which Jews of the first century were ignorant.
