Lloyd-Jones classifies a particular group of people with the following description:
In the natural realm there is the type of person who tends to be always analyzing himself, analyzing everything he does, and worrying about the possible effects of his actions, always harking back, always full of vain regrets. It may be something that has been done once and forever but he cannot leave it alone. He cannot undo what has been done, but still he spends his time analyzing and judging and blaming himself (17).
This group may tend to bitterness, and has the obvious tendency to morbidity and introspection.
