I don't want to bring myself down to place where there are hard and fast rules. In general I try to be compassionate, but that is dependent on the moment ultimately.
The hardest part is when you're in danger yourself. You have to face what could happen and might be likely to happen to you. It's not just that you're there standing next to somebody that something bad is likely to happen to. That is a true moment of reckoning with who you really are.
