Even if you cared about legacy, realistically, how many people are remembered for more than a few generations, if they are remembered at all?

Even the majority of the leaders of nations are only remembered by historians, people with a high interest in history and briefly by some students studying for their next test, and these will be mainly the leaders of their own country. Unless they did something exceptional good or bad.

And then there are a few exceptional high achieving writers, inventors, scientists and academics. Even within their field most become irrelevant and forgotten after a few decades.

Some ordinary people who did extraordinary things might also be remembered.

But if you compare that to the enormous amount of people who have lived and died, basically no one will be remembered after their death. I’m not making excuses for the bad behaviors of horrible people, I’m just saying that losing all relevance and not being remembered after death isn’t special.
