The thing is, if you don't have empathy, how can you deliberately cause hurt?
I have tried to explain it as the difference between selfishness and self-centred-ness. So if you are selfish, you do things for yourself regardless of who you hurt. If you are self-centred you don't realise that you are hurting people.
So some people who lack empathy may genuinely not think through the consequences of the appalling things they do. Does that make them evil (as in doing things to hurt people) or self-centred (as in doing awful things that hurt people, but doing them for self-satisfaction rather than to hurt others)?
The kids who killed Jamie Bulger are good examples of this. Did they kill him deliberately, knowing he would be hurt, and dead, and his parents and society would be horrified by what they had done? If they had done it knowing the result, then yes I suppose you could say they were innately evil.
But I don't believe they did. I believe they were abused young kids, with very little empathy and understanding. I believe they acted on impulse and out of curiosity, with very little perception of the end result of their actions. They wanted (possibly out of curiosity) to see what would happen, they happened to find a child, they were sort of experimenting.
What they did was appalling by normal standards. And obviously horrifying to the majority. But did they really know what the end result would be?
To be evil, a person would have to deliberately cause harm. They would have to know the harm, to realise what the end result would be, to be able to empathise with the person they were hurting, and with their victim's relatives.
I suspect many psychopaths don't have the ability to do this; therefore by definition they are not evil.
And I think
