Okay, does Hussie have something against children? In Homestuck proper, most of the dying happened to the beta four when they were thirteen, and in Hiveswap it's always been the very young-seeming trolls who die in the bad ends (Diemen and Boldir aren't confirmed to be very young but they definitely look young to me, and Tirona's confirmed to be little).

Alternia is fucked up and doesn’t care about you regardless of age, also I guess children getting killed in media doesn’t happen as much so we’re not as desensitized as we are to other kinds of violence.

Also all there’s a good lot of adult death in HS too. And just. Everything death.
