I just blanked, and deleted
http://en.wikipedia.org/wiki/List_of_famous_people_responsible_for_a_death
We had names of many famous people, stating they were responsible for someone else dying. ** Not a single reference **
Well done. You have improved Wikipedia.
Anyone saying that article shouldn't be speedied is just wikilawyering. Try genuine lawyering, which would tell you that such an article is borderline illegal. If that's not a good reason to speedy something, then I don't know what is.
In many cases it is fine to essentially use the Wikipedia articles as the sources for the items in the list. In the case of accusing people of killing someone, it is absolutely not.
