i have all sorts of ways of dealing with this type of thing and it's never consistent.
If a rock band member has died that i saw on stage, i never listen to their stuff again, i just can't, because the music never again evokes the emotion that it did originally.
With family that have passed, i make a point of carrying on their traditions, it makes me happy, sad and a whole lot more but i get a lot from it. My family are aware of these traditions so it's quite possible that they will continue for generations to come which is thought provoking in its own right
