Whatever the reason might be for us remembering, my point still stands that by retelling the story we make it so that disrespecting others and their belief was indeed the right thing to do for him to be remembered, that is what lead to his goal being reached. If the same thing happened but the story wasn't passed on, then it would not have been the right path to reach his goal. For a modern reference, that is why I'm a strong supporter of not propagating the names of people committing things like mass killings for glory, like we've seen quite a few times.
