I believed human life should be valued yet it seems dispensable in the grand scheme of things

How is it one life is more important than another? Why are people dying every day from weapons and decisions made by governments and wont be affected by their actions? Life is like that I guess and despite our humanity, it seems dispensable. For example, what if I die tomorrow or a year later? Would that affect anyone aside from my family and friends? Life will still go on. Isn’t it also crazy how life can just cease to exist? Like your memories before u were a kid or like how you can just stop being conscious. Life seems so hmm fickle

Anyway just some of my own rambling.
