He didn't.
Ask your parents :)
it was not so much his actions as his rhetoric that caused the deaths.
It depends on your opinion of the two. Adolf Hitler caused many more deaths (millions more, in fact) and discriminated against Jews, whereas Osama bin Laden gave away plans of the World Trade Center to a group of terrorists which he joined. Bin Laden hadn't directly caused any deaths but there were many indirect ways in which he was suspected helped along terrorist attacks. Personally, I believe Adolf Hitler was worse.

Yes, you could say that, as Mao was responsible for more deaths (largely through famine he caused) than Stalin or Hitler.
70,000 deaths were caused
I think not. Maybe by some, but he caused a lot of deaths. Escpecially Jews. He never did like them. Then he killed himself so that he wouldn't be caught.
Deaths caused because they thought someone was a vampire: a few hundreds, possibly. Deaths caused by people who thought they were vampires: Several tens. Deaths caused by vampires themselves: none.
Hitler ordered the imprisonment and deaths of millions of Jews in Europe.
None. Like abortion, deaths involving firearms are caused by people.
430,000 deaths are caused by smoking each year.
It is not known how many deaths are caused by artichokes every year. It is possible that artichokes do not cause any deaths.
