Re: Did the Voyager crew make the wrong call in Memorial? "
Of course numbers matter if you want to compare quantities - how many are affected and need the monument. The more people that are killed the bigger the part of society that needs to deal with it. (That equation has its natural asymptote when there is no one left of course.) But I don't think it is really about how many people are affected but how much they suffer from this. And you are in a way right with the examples about the Romans and so on. The longer these things are in the past the less its possible to connect to what happened. And another problem is that you never know, if its just one side of the coin. Even if you are actually experiencing the memory - who tells you that that's the truth?
