How they became psychopathic is their case but it may never be addressed. Criminals and immoral people need help but don't usually recognise that and indeed will resist enforced change by fixing their identity even further. Essentially, though, they are people doing the best they can, but in a severely aberrated mind-set. Any change needs high quality, empathic communication. Remember that a Muslim's idea of right and wrong might be very different from a Christian's or a modern enlightened person's ideas.
Tolerance begins with understanding.
Understanding requires communication and empathy, but not necessarily liking or agreeing. You're quite right to point that out. It's a question of what is the feeling in your mind when you say it, whether it is a compulsion that rules out choice or not. I meant 'should' in that you need to respect her rights in order to be rational and not hypocritical, not 'should' in that you have to, or feel driven to, or have no choice but to. IF that's where the problem lies.
