What is the exact word/phrase for following kind of behaviour?
One person has already been to a crowded place and the person thinks that he is highly likely already caught the covid virus infection from there (no symptoms yet or has not tested positive). Now this person does not wash hand with soap saying that he has already done riskier things and what is point in washing his hand with soap or follow any precaution any more.
I would like to know what this kind of mentality is called when a person thinks (there is no proof that his thoughts are hundred percentage accurate) everything has already gone bad so it's ok they can do anything even if that can make the situation even worse.
