These so-called "Good Samaritan Laws" are a moral concept that exists across much of Europe and omission of help is actually codified within Article 223-6 of the French Code of Criminal Procedure, such that...
"Anyone who, being able without risk to himself or to third parties to prevent by immediate action a felony or a misdemeanour against the bodily integrity of a person, wilfully abstains from doing so, is punished by five years' imprisonment and a fine of € 75,000.
The same penalties apply to anyone who wilfully fails to render to a person in danger any assistance which, without risk to himself or to third parties, he could render him either by his own action, or by initiating rescue operations."
