Tips
history
From Zeng Pu's 《孽海花》 (late Qing): '这种人要在敝国,是早已明正典刑,哪里容他们如此胆大妄为呢' — 'such people would long since have been executed in our country; how could they be allowed to act so lawlessly?' The phrase captures outraged condemnation.
usage
Sharply condemnatory — used only for clearly wrongful actions. 妄 ('wildly, without principle') is the key morpheme that makes it negative; compare neutral 胆大 ('bold') or positive 胆大心细 ('bold but careful').
