How many are metaphorically in love with Death, versus literally in love with a woman who is Death? Because the first isn't the same, and the second is still a pretty silly motivation in my opinion.
Dude people in real life believe the Earth is flat and that there's a gigantic conspiracy among all the world's goverments hiding it from us, the fact that cosmic artifacts exist isn't going to stop some dude from going crazy due to his insane belief system because that's kinda how being a fanatic that's convinced you're right works.
Second, the barely coherent ramblings of a homeless wannabe artist convinced an entire nation that a particular religious subset was behind all there troubles and needed to be exterminated and launched a world wide conflict over it, and he didn't even have the benefit of being one of the most powerful beings in the Universe to really talk people into it. People will follow lots of things.
