Is Google Censoring The Word "Evil"?

A search for "Google is evil" on Google finds an estimated 2,300 results. However, the same search on AltaVista finds 158,000 results. The same search on Ask.Com finds 7,300 results. However, if Google supposedly covers a larger proportion of the web then Google should find the most results. Could the difference be explained by differences in spidering or estimating the size of the results? Or is Google using the code which is used to censor Chinese queries?
