I'm Having Trouble Cheering for the Bullying of Bullies; Do I Need Therapy?

So, the tl;dr on this: A teenaged girl is being bullied at school. One evening when she's feeling especially low on Twitter, a pair of these bullies start hounding her to cut and kill herself. Some folks (evidently from Anonymous, or some similar group) swoop in to her defense--by threatening and hounding the bullies.

On the one hand, we want to say "Yeah! The Internet does a good thing! Protects damsel in distress!" but on the other, this really looks like a bunch of adults coming in and bullying two other kids (albeit ones who are being assholes and--regardless of whether they understand the repercussions or not--dangerously goading a classmate; I'll set aside the weirdly racist/homophibic/sexist overtones of the counter-bullying).

As a male-type person fully acquainted with the low impulses of male-type people (and obviously assuming these counter-bullies were likewise male-type people) I have to wonder: Were these saviors roused to righteous anger by the cruelty of these bullies, or was their righteous anger casting about looking for a justifiable target? Does a notion like "forcing them to do the right thing" even precisely make sense? And why does this all make things like this headline gong in my head so damn loud?

I'm going to level with you, Internet: This doesn't seem like progress, somehow. It just feels like that time Mike Tyson got pissed at a reporter and, in the midst of his tirade, shouted: I'll fuck you 'til you love me, faggot!"--a phrase that always comes to mind when I hear people talking about how we can bomb our way to peace, or how the *real* solution to movie-theater shootings or sexual assaults or police brutality is for everyone to have a gun all the time.
