Characterized by bad, misguided, or harmful enthusiasm or zealotry.
From Greek 'kakos' (bad) + 'zeal' (from 'zēlos' meaning fervor). This rare adjective describes enthusiasm that is misdirected or counterproductive.
Cacozeal perfectly captures the irony of someone working incredibly hard toward a terrible goal—it's the enthusiasm itself that's problematic, not the effort, making it distinct from simple 'bad intentions.'
