A quote from the creator:

Malbolge was truly created with the idea that programming should be hard. It should be as close to the Infernal as a ProgrammingLanguage possibly can be.

And another quote:

Users are encouraged to make their own, unique homebrew versions of Malbolge and Dis, in order to achieve the kind of portability problems normally associated with major languages.
