Have you ever tried to fix yourself by breaking someone else? It doesn't work very well, does it? Sometimes it's person-specific... maybe they hurt you, and you want them to hurt back. Sometimes it's a lot more general... you're having a crappy day, and gosh darn it, if the world isn't going to have a crappy day too!!
The thing about breaking other people to fix yourself is that it's a lot like emotional eating. It gives you a bit of satisfaction for that moment that you're engaged in it... but when that moment is over, you're left with guilt and regret --- and have done absolutely nothing to fix the problem that you were trying to solve in the first place.
Breaking someone else to make yourself feel better is a little like that. It fills an ugly little hole in your heart for a moment... but it's an even uglier fix to a problem that you still haven't solved -- only created new ones on top of your brokenness.
So what can we do?
First, I think that we have to recognize that we're even doing it. You can't stop something if you don't know what it looks like. Just become aware of it... even if that's after you've done it. But at least become aware.
We have to think of ways that we can create the same emotional response other than making them feel bad too. Then, before we open our mouths, we can stop, acknowledge that we're looking for that response, and choose a different mode of getting it -- preferably one that doesn't hurt someone else.
And when we stop creating more problems for ourselves all the time, we can actually go about the business of healing the wounds that needed the emotional salve in the first place.
We can fix ourselves without breaking others... in fact, maybe it's the only that we can.
