regarding the lore and why some killers don’t have much (mainly killdroid)

harken and artful gets alot of lore/facts while we get absolutely nothing for killdroid, lizzy, sarah, sulfur and cobalt, and the toolbox i think they should focus on other characters instead of just artful and harken cause it’s actually fucking stupid that they get most of it this is serious getting old (i know lore isn’t a main priority but at least give us something about them idc if its the littlest thing i’ll take it.)
