I don't think this is a particularly good point to make. You're saying that since X happened and since X is worse than Y, we shouldn't care about Y. There's been school shootings so single murders don't matter? There were so many more deaths in world war two than in world war one, so WWI doesn't matter? And this is ignoring the fact that your "worse" claim was based on your own personal ethics which is, at best, subjective.
