Insulate in the Framed Corner?

The last stud cavity of my outside wall is mostly covered up by an adjacent interior wall with only about 1/2-3/4" gap floor to ceiling. Where the outside framing butts up against the foundation wall there is obvious air leak (I'm pretty sure the "builder" didn't use any foam sealers anywhere). Now, I may be able to find some clever way to reach in to seal the air leak with some caulk, but should I try to insulate this 6" x 6" cavity or just seal it completely off from the rest of the world?

Cut one of the corner studs out by slicing off the nails at the top and bottom with a reciprocating saw. (just look out for any electrical wiring) Then insulate the corner and put the stud back in.
