Why did ARM create a 16 bit version of their normal 32 bit instructions?
As said, each 32-bit RAM fetch will pull in two instructions instead of one, which reduces the time spent waiting for memory accesses to complete.

Also, 16 bit instructions take up less memory and cache which could be critical on a small device.
