some countries allow for the mistakes of youth in not influencing the rest of one's future life
True. There was a Cabin Manager, at an airline I used to work for, who murdered his parents when he was below the age of criminal responsibility (at the time, in his country). He won some TV game show many years later and was outed due public interest as a contestant. The airline then sacked him for not declaring his “criminal” history. He appealed the dismissal and won his case, on the grounds stated. During return to work refresher training, which was required due to his prolonged absence, he took to social media and made some anti company remarks. That was sufficient to ensure his second dismissal (for Gross Misconduct) stuck.
