rottenly

In corrupt fashion

In a rotten manner—poorly, badly, or with decay.

The word is rare, since *rotten* itself often serves as an adverb in casual speech: I slept rotten last night sounds more natural than I slept rottenly.

When it does appear, it emphasizes moral or qualitative failure: He behaved rottenly toward his family.
