A vicious cycle is a cycle (meaning it never ends) of usually revenge (though anything bad can be considered vicious as well, such as a spiral of bad luck). Like if X kills Y, then Z avenges Y by killing X, but then A avenges X by killing Z. And continuing as such. There is no break in this chain, and thus is called simply a cycle.
