Languages can definitely change and they can diverge. For example, Latin split up into the modern Romance languages: Portuguese, Spanish, Romanian, Galician, etc. This is less known, but languages can also converge: those languages are called creole. Some people argue that English is also similar to a creole: a mix of Germanic and French.
One factor behind the divergence in the two versions of Korean was the North's decision to purify the language by eliminating the many words of Chinese origin and coining new native terms to replace them. In South Korea, Sino-Korean words still comprise more than half of the vocabulary.
