I think they do try to do something OK. There are some huge animal abuse cases in some countries. Stray dogs being burnt alive (as a mean of euthanasia, while some people put the money in their pockets and "solve" the problem for "free"), there are animals being skinned ALIVE for some very expensive fur coats. I just don't want to give you links to such videos since I wasn't able to watch them either. For such cases PETA is a good thing. Sure sometimes they tend to go overboard, but I think mainly they are OK
