As a lawyer, I would have thought that you'd understand but apparently not. Describing a person's motive is not empathizing with it.
No matter how bad the abuse might have been or was perceived to have been, it does NOT justify the cold-blooded murder of this bishop. No Flying Inman would disagree with that conclusion. It might explain why he felt that he had to take this action BUT IN NO WAY, SHAPE, NOR FORM DOES IT JUSTIFY THE MURDER.
There was no abuse.
