Here's my .02$ worth, for all that it matters.
There is a ... trend?.. Notion?... Social More?... related to "Helping the less fortunate" that involves saving the willfully stupid from themselves, and considering this heroic, morally justified, and desirable.
This is distinct and different from protecting the mentally infirm (such as people with learning disabilities, or people who have developed cognitive impairments through injury or disease) who have a genuine physiological reason for their impairment. It is extended toward people who, simply for lack of situational awareness, lack of sense of danger (because they have never experienced dangerous situations, due to being bubble-wrapped in the protection of society, or a number of other factors), or lack of a sense of self-preservation, are a menace to others and themselves.
This .. notion.. (for lack of a better term) directly implies that failure of the more aware to cover for and protect the less aware is equivalent to willful endangerment, or gross negligence, through applying a false equivalence that the people being protected are on the same grounds as the infirm. This leads to a pathological spiral, where more and more people need to be covered and cared for, as the impetus to be self aware diminishes, through revocation of consequences for irresponsible behavior. (See also, "Affluenza")
The remedy is not more protection from society, or loving pats and a "There there, it will be ok little baby" type pablum. The remedy is an abject lesson in real life, personal responsibility, and consequences.
Perhaps letting them go on the safari is a bit extreme as a first brush with such consequence-- give them the opportunity to wake up from their dreamy rose colored world, and be rational human beings first-- but I can definitely see how a "Yo, the animals are real and will kill you, stay in the car" should be sufficient warning if someone takes such a trip. If they STILL somehow fail to understand that they should not roll down windows, get out of the car, and try to put their heads in lions mouths for an "awesome selfie", they clearly deserve the gristly, bloody end the wildlife will give them.
Again, this is distinctly different from protecting the infirm; The caregivers of such people should not take such individuals on the safari to begin with.
