While it is theoretically possible to drive a bus over those who have caused you pain, I wouldn't recommend it. A jail cell can be a great place to collect your thoughts, but it gets quite boring after a while. (Imagine a little smiley face here.)
What you say has a nice bit of dark humor in it, I also seem to hear two different intents?
Telling the truth can be cathartic, and maybe even release you from some pain. But to tell the truth with the intent to punish seems a bit like entering into battle. Maybe that's okay, but more importantly, does the latter serve your needs as well as the former? You need to do what's best for you, but "best" is a very big word.
If you tell the truth through details and events but without spinning your personal pain into the mix, your readers may visualize your pain on their own terms--sometimes a much more potent thing than were you to describe your pain on your terms.
Okay, now here's me trying to go deep:
Pain is sort of like a hot potato--you can pass it off to someone else, but it always comes around to you again.
...
And this thought is perhaps a bit more coherent:
Abuse and the pain it causes is part of our culture of violence. The most important thing (to me, anyway), is to break the cycle of violence. Violence, pain, abuse, or revenge, in any physical or emotional form, ultimately causes more of the same.
Added edit: Oh, and I should have said that PinkAmy's comment above is much more practical than anything I've written here. The first step is to always write, then think later.
