Either your "very strong will" is far stronger than one may think at first, or your whole world is filled with weak willed people. Maybe it's a combination of both.

In my case it's not very clear how Saints appear. Some say that it's just a mix of luck and determination or strong will... Most seem to think that there's some kind of destiny involved and others just think that it all comes down from the very first Saints who ever existed and how their souls keep reincarnating. But sometimes there have been almost all the 88 Saints there can be and other times it has been barely a bunch of them.
