I have sympathy for both.
Rebecca was from the UK, and that apparent poor decision-making and lack of maturity in a 36yo is a symptom of the malaise generated from the UK's "health and safety" obsessed Government and society. Nothing that can be controlled by legislation is allowed to be dangerous, everything is "safe".
UK citizens growing up are kept wrapped up in cotton-wool and told repeatedly that the state is responsible for their well-being "from the cradle to the grave".
The result is that many UK citizens do not learn how to take care of themselves nor how dangerous the world can be, so a 36yo who has not learnt how to make life-saving choices when allowed out into a freer environment is very, very sad, but no surprise.
R.I.P. Rebecca.
