I never say the pilot shouldn't take a blame. What I said the company or whoever hired the pilot should be sued for being incompetent, they are the real c*nt. You are confusing with a requirement to be a pilot such as license with a set of rule that the pilot & passenger must follow for safety such as seat belt and etc.
Of course he would be charged because he drove a plane without a license, that's a requirement to be a pilot. However, the company will be sued for hiring a pilot without licensed, they are the one who holds the big responsibility.
It's the pilot responsible to ensure the safety of his passenger for example put your seat belt on. However it's the company's responsible to hire the right man with minimum standard requirement such as qualification. You don't look at the qualification based on CV. You can lie about your experience but you can't lie about qualification. Company won't keep track their experience, but company can track where & when the pilot got their qualification.
If the company never set a rule of the standard hiring people and to make sure check the qualification then it's the company's fault. If they did set the rule and the person who hired the pilot decided to ignore it then it's the guy who hired him being responsible.
There are tons of people can lie, this pilot is not the first one in this world who lied when applying a job. That's why they need to be checked because this is a matter of people's life. What an absolutely lazy & incompetent whoever decided to hire the guy.
