In all reality though, I don't know if children could handle the thought of ever impending death. Climate change wears on me now and we have a few years before things to start getting too deadly. Having the belief that there is safety when death is guaranteed isn't the worst thing. Like telling someone they are going to be okay when they clearly are not going to survive. They are already going to die, why scare them if there is no benefit to doing so? Ignorance really is bliss.
