I was wondering if there is a word used to describe someone who starts arguments just because they get enjoyment/satisfaction out of it. And I don't mean a friendly debate I mean actual arguments, like a fight. I feel like there is a word for it but I can't think of it and if there is no word then I am going to make one for it :). P.S. "Devil's Advocate" is not the word I am looking for.
I'll tell you what I use.
See firebrand defined by Merriam Webster as
one that creates unrest or strife (as in aggressively promoting a cause)
There are also simple words such as agitator, trouble maker, rabble-rouser.
It may not quite be the word you are looking for, but pretty close...
