It seems to me that we really do need to develop spiritual fortitude for these times.

Even people who have received special training in ethics will lie to be able to fit in with a system or to avoid things they don't want to look at or talk about. Then you have to deal with the betrayal because you've been lied to. Even very good people do this. And then, sometimes you are in denial about that for a little while. Maybe that's what you needed to do to get through life for a period of time. But there are many time when being in denial about it is just going to make it worse, if it goes on forever. All of the humans, even the ones who are supposedly trained not to do this sort of thing, are susceptible to repeating old patterns. Painful truths are more easily faced when you can believe in some kind of spiritual fortitude, something that's beyond human capabilities.
