Akrasia is somebody "lacking command (over oneself)"), occasionally transliterated as acrasia, is the state of acting against one's better judgement. The adjective form is "akratic" .
Aristotle reasons that akrasia occurs When people are conscious of their own failings and desires. Even though they act against their better judgment they are aware of their faults. That's my take. Check out the following link,
