/lit/ - Literature

Do you understand the following? I posted it in /adv/ but they say they can't comprehend it. It makes sense to me. I told them to read it slowly and carefully but they seem too stupid

"which came first in sadomasochism?
sadism - because you feel bad for hurting others, thus seek out 'deserved' punishment for yourself
or
masochism - you feel like you deserve to hurt others after putting yourself through a lot of pain first / you feel like you've been duped somehow into hurting yourself and now you want to take out revenge on others

is that how sadomasochism works?"
