Umm, it's not all pointless.
I got in a fight with and beat the crap out of the cockless bastard who seriously lied about having only a few weeks left due to Hepatitis C to make my girlfriend of 3 motherfucking years dump me to "make him feel better while he passes", and it didn't fix anything, but it sure felt good to beat him senseless.
So far they've been together for 6 months and his "fatal case" of Hepatitis C has magically degraded, in steps, according to what my ex is willing to do with him to him being an inactive carrier of A Type who can't pass it. Apparently she realised just last week that he's been lying to her about everything (She only did it because he convinced her he's the only person in the world that could truly love her and only her, and that he has absolutely no interest in sex) when she found pictures that only a slathering DUMBASS would keep on the phone that he lets her borrow. Turns out, yes, he have a MASSIVE interest in sex with multiple girls at once, and apparently is into photography.
She came to me, I got to have a delicious "I told you so" moment out of it (I didn't actually say it), and on her request, I didn't simply ignore him when he tried to start something again. It didn't end well for him that time either.

No no, it's best to have the decent people only be as violent as they need to be.
