The death tolls are easy to find--e.g. Inquisitions, Fitnah, &c. The upside is a little less spectacular. Either is subtle.
Beyond that, it's all in how you treat it. There was an article--long lost to the mess of the web--a few years ago about a prominent Anglican minister who sought "new ways" to deal with faith crises, including drugs and domestic violence. Now, to me, a preacher calling for the church to examine the causes of domestic violence in order to do more than simply provide a refuge for battered women, is a good thing. Others will exploit the notion of how it came to be that so many religious men are beating their wives.
So if you just want a litany of services, check with the usual sources: Salvation Army, St. Vincent de Paul, and other relief and charity organizations.
Other than that, though ... pick up just about any decent tertiary examination of religion (e.g. Elaine Pagels, Karen Armstrong, Jeffrey Burton Russel, &c) and you can find the source documents (e.g. Tertullian, Irenaeus, &c) from the notes.
What you're actually proposing is a rather complex undertaking. The superficial wounds and benefits attributed to religion are generally inadequate for seeking the whole picture.
To the other, I might be wholly on the wrong vein. Perhaps you can tell us a little more about the project?
