I think the need to have someone be inherently evil because they caused someone harm to be a bit over the top. Certainly one can be harmed and believe the person causing the harm to be bad or evil but that need not translate into totality. Nor does it invalidate harm experienced by any individual. I think looking for inherent evil just makes it more understandable or cope-able by the person who experienced it. It need not be universal nor inherent to hurt and cause damage.

In a relative sense, it is perhaps coloured by my personal experience with CSA(and I use the A here very loosely). The guy, in my case, was not, in my opinion, evil. The experience was not horrifying to me at the time. Susan Clancy's book helped me a lot.
But to condemn him as evil simply because he touched me as a child, in my case, would be inaccurate. My experience does not invalidate those for whom CSA was horrifying and shattering.
