One of the inmates I knew had raped little boys and the inmate was HIV positive. So they released him from prison.
This sounds a wee bit nonsensical, and your post drips with emotion. I too find myself really stirred up about the injustice and cruelty of it all, and I've learned over time that those people and things I cannot change, I pray for and then
avoid.
Perhaps a change of scene would bring more joy to your life--sounds like you've "paid your dues," maybe working with a group a little less (don't know what word to use here, but you get my drift) would bring you more job satisfaction.
Best wishes!
