Even if the language is compiled, you still need a runtime. GHC compiles to native code, but there's still a runtime for instance to handle the garbage collection, to sort out the lazy evaluation, and to translate the blocking IO API at the haskell end into a non-blocking IO api at the kernel end. I surely wouldn't want to be debugging my haskell code on a time budget by directly looking at the machine code that is running. I know some people do that and it can be quite illuminating, but the fact that I can debug haskell in its own terms is good.
