Can I cut this (log house)

[Hillpinch]

I want sloped ceilings all the way up to the "ridge" and I'm wondering about this. Can I cut it flush with the wall on the right?

No, you shouldn't do that.
At the same time, it's a bit difficult to see with the few images.
Otherwise, it does look nice with visible beams!

I was also thinking about keeping it. It is a bathroom so it will be a bit of a special solution then. Otherwise, it will have to be a ceiling there.
