In the book
The Head in Edward Nugent's Hand: Roanoke's Forgotten Indians by Michael Leroy Oberg, at least some Native Americans had a view of one of the supernatural beings as mischievous and undependable rather than evil, perhaps similar to the idea of the coyote trickster although they did not use that language.*
So, maybe a monotheistic religion not so much into eventual perfection but which matter-of-factly accepts the idea that people are people. And which has insight into the idea that negative prohibitions feed into a self-fulfilling prophecy and are counterproductive. Just like if an old-line Baptist minister spends twenty minutes railing against the evils of cardplaying, well, heck, I could have gone all day without thinking about cardplaying once, just don't remember it being all that exciting, but thanks for kind of reminding me that it sometimes is!
And as far as a Messiah? Well, we tend to be at our best in response to such disasters as earthquakes and floods. It's sudden, abrupt, and when it's over, it tends to really be over (some exceptions of course). We're not at our best in response to droughts and famines. So, maybe the Messiah is a leader who helps people handle famine much better than average and it's talked about for generations. And as a result, his religious teachings are taken much more seriously.
So, a religion which rather takes the approach, if you make a mistake, just try again the next day. A religion very practical in a number of regards.
=========
Now, there's already Santeria, which I think is a mix of Catholicism and native elements. And there's voodoo, which we think of as wholely bad but I don't think the practitioners think of it that way.
But, even the few elements I've sketched out, I don't think there's a current, living monotheistic religion where that's the main approach. And you yourself could probably also sketch out a few different elements and find the same result of no current religion. So, I say, always room for one more!

* Kiwasa. So maybe instead of waging war against ourselves, a more bend-the-path religion.
