Since I write about social issues, I have to say something about pedophilia. It is mandatory for the times we live in.
I have no training in mental health, but I have training in understanding evil, so I will say what I know about the topic and speculate about evil v. mental illness as it applies to pedophilia.
Pedophilia can have several points of definition, legal, moral, medical, social, etc. all with the underlying notion that pedophilia implies one person taking advantage of another person of a vulnerable age group, which in the case of sexual penetration, creates physical or emotional damage to the child, or a pregnancy where the child-parent simply cannot be a competent parent to the created child.
And we must make a distinction between mental illness and simple evil. While one can be both mentally ill and evil at the same time, some acts require evil to commit. We should not try to label evil as a mental illness, much less as a socially-acceptable behavior.
This topic will require several articles.
