Nice spot! All fixed. Cheers!
しまう has two main nuances: ‘Accidentally’ and ‘Completely’. More often than not, you’ll find that they’re almost interchangeable.
In this particular sentence, it’s combining both きる and しまう to make the ‘utterly’ nuance, since it’s something like ‘absolutely finished’. Hope this helps!
