I agree with both of these points.
I think it's important to note that the typical view of a god ( at least most Christian views) are of a perfect, omniscient being who is not bound by Intents. Comparatively, Sazed is just a mortal who took the shards and while he did have his copperminds, he was far from omniscient. He did what he thought was best, and it didn't turn out perfect, but can you blame him? He doesn't instinctively know what he should do. Couple that with the fact that the opposing nature of the two shards make it hard for him to act, and you can see why things turned out the way they did.
Also this piece from BoM,
I think this is important beacuse maybe Sazed does interfere more than the people realize. The only viewpoint characters we have are regular mortals, none from Sazed's view, so I think its a very real possibility. Overall, I think he has done a pretty decent job.
