The sex, it turns to children, then the children turn to villains
Villain wolves screaming kill them all, fuck 'em all

from Mellowhype (Ft. Frank Ocean) – Rico Lyrics on Rap Genius

Meaning

Having sex will eventually lead to children, these children will be born into bad conditions and thus turn into drug dealers, gangsters, etc. (villains) and apparently all the villains end up in the Wolf Gang and just scream fuck everything, kill everything
