That was more disturbing because of the apparent cultural acceptance, amongst each other, of dehumanizing and raping a person and pissing on them, and jerking off on them, and they all laugh and cheer about it, and post a bazillion tweets, instagrams, & YouTube videos incriminating themselves, not thinking twice that that's not a good idea, let alone the fact that they obviously do it because, at least in their minds, their peers will think they're cool for doing so. You know, as opposed to the human reaction, which is to be shockingly appalled.
