I grew up with a religious nut of a dad and a very spiritual mom + it's Buddhism no less, and in Buddhism you're taught a lot about various non-self concepts including things like your life being one among many cycles, karma, and non-attachment. A Buddhist story my dad brought up when I was younger was that of a woman who had lost her son but took it with what the uninitiated would register as apathy, but he says was wisdom due to the understanding of the cycle of life and the implementation of non-attachment, to the self or others. Emptiness, clear your mind.
I was told from a young age about the cycle of life and death and thus was quite desensitized to it for a child, and now that I know more about life and death itself on a more 'scientific' level (as opposed to it being a flowery or karmic concept) I find that having had an awareness of an 'ending' from a young age has made me regard death more calmly than I see my peers do- news of death is not shocking or saddening, especially if I don't know the person (or even if I know the person). There is no dark morbidity or fascination, just nature, like watching the sun rise and set. Most people probably reach that point in their life, I was just exposed to it much earlier. My brother is the same. I don't actively consume or pursue the media, but it is a happening of life as much as living, eating, or doing whatever else, just one with a very permanent outcome.
