I checked the vids - for which thanks. I found the comments (I only checked the last 4 years, which I copied (58 pages). Now I'm going to have to read through it all.

As I suggested in my comment here, even empathy is not the answer - it is just an answer.

I posed this scenario in my story: Robert senses children being abused in a brothel, and he interferes. However, there is one customer who tortures little boys and Robert forces empathy on him. The same man returns and tortures another child. Robert invades his mind and discovers that empathy is making the pain of the child even more of a pleasure for the man. It turns out he too was treated this way as a child and saw what he is doing as being good (natural) for the child.

Empathy is not an 'island' that floats on its own, it is affected by our personalities, our experiences and belief systems.
