I don't think it's that accurate. Evil people are rare - and lazy people usually don't cause problems. The most real damage comes from human stupidity - from the mass of people that just want to help and do something good. Stupid People blindly believe anything they're told. And they do a lot of really bad things not because they're evil and lazy, but because they want to help achieve even the most stupid goal. Usually even nasty propagandists leaders aren't that evil - often they're just an intellectual failure - or have some mental issues. Themselves they don't do much practical evil - the mob of nice stupid people does the dirty work, because they just want to help.
