Counter-productive. Well, most things with counter as the prefix. When someone's dead you don't say they're counter-alive do you?
No, but there's no good reason why we couldn't. If we all woke up one day and agreed that counter-alive was a word then it would be. Language works by consensus, not consistency.
But in fact there is a good reason we don't say counter-alive. You see, "counter-" as a prefix means "opposed to the process of-". Since we tend to see being alive as a state not a process (notice how you say "
being alive") it would be silly. That's what "un-" is for; the opposite of the state "-something". Such as unintelligent - the state of not being intelligent. But then there's "counter
intelligence". Intelligence in this sense means a process - the gathering of secret information. Thus, counterintelligence means "opposition to the process of gathering secret intelligence".
But there's another reason: we already have very common words to express the idea of counter-alive: dead; and dying. Dead is the opposite state to life, and dying is the opposite process to living (thus, there's no need for counter-living). While the English language revels in creating more synonyms where none were needed, no language strains itself to create new words for old ideas. This is why we find "counterproductive": there really aren't that many near synonyms for the idea, and those near synonyms aren't near enough.

Discounting the archaic words no one would bother using anymore (when did you last say "malefic"? I've read it once.) and the words in that list that aren't really proper synonyms at all (95% IMO) the rest just don't quite express the idea. Harmful means something slightly different (an implication of actual harm rather than just opposition to the process of being productive) for example.
English fascinates me because it keeps making new words by attaching prefixes and suffixes to old ones (nation->national->nationalise->nationalisation->denationalisation->antidenationalisation...ok, it got ridiculous at denationalisation).
