I think my sister has some kind of pain fetish

Yesterday I was using my sisters laptop to write a paper, and when I was researching all I see on her search history is "avengers fanfic peter stabbed" "Naruto impaled fanfic" "mha todoroki gunshot wound", and much more. And im just like did I read this correctly? And the fact these are her favorite characters. idk this is just funny to me, but I won't judge cause what I read isn't any better.
