Carnage is a serial-killer and he drills his pet dog to death on=panel in the comics, as just a start.. the problem with Carnage is Spider-Man as a whole is not a mature franchise.. can't argue that.. it is specifically geared for younger audiences, so that's a tricky one.

Valeska however is from Batman and despite the 60s making Batman campy the original Batman stuff was definitely mature and came from the pulp era of comics when death, torture and so on was common on-panel.. though I don't think many of the Joker pages are marked as Mature.. so.. again.. tricky.
