Personally, I think Jesus existed as a regular person. But I don't think you have to "eschew reason" or be "driven by ego" in order to not believe he existed. We're talking about a guy whose life is barely recorded. If someone was to say Pope Francis doesn't exist, that would totally be eschewing reason. But a guy who lived two thousand years ago who we know almost nothing about, questioning his existence shouldn't be so uncommon.
I've seen people get mocked for being religious, as they should. We should have a society that shames people for choosing to believe lies, especially when those lies harm society. We mock people who believe vaccines cause autism or that the Earth is flat, why not people who believe in a god?
Again, this isn't eschewing reason or being driven by ego.
