I don't think there is any doubt that you could be right, but I would say it's also possible that you are not? Neither of us can know as only Bolton himself knows if he is creating sensationalism to sell his book. For example, the simple truth might itself be so shocking he doesn't have to make anything up.
But the important thing to me, since I care more about you than I do about Bolton's real character, is to wonder how it came to pass you have such a negative view of other people's motivations. I'm wondering, for example, if your high love of the good might not be the result of fear of failing to live up to standards set by your parents. I know for myself the fear of disappointing them was tremendous and that my father also was very much like you in that he distrusted everyone.
Now I know that when it comes to negative attitudes toward other people it might seem my point of view is negative, that we all motivated by a need to remain unconscious of the fact that we hate ourselves, but I just see that as fact and not really negative at all because we only believe what we believe because we were made to believe in a lie. There is nothing really wrong with us and that most of the evil we do is out of a misplaced belief that we know what really is the good. There are, however, people who are so badly damaged by their self hate and feelings of worthlessness, they live for the revenge of proving it to be true by doing the despicable. But that isn't everybody or even most people, in my opinion.
In shout, human nature is sourced in three different parts of the brain, the primitive reptilian, the nurturing mammalian, and the social cultural human brain that can conceptualize and empathise. People differ in how much and how properly each is developed. They say we are created in God's immage. If so a reflexive negative attitude as to what a person is may be spiritually inappropriate. Does that make any sense to you?
