Minus the times when the other person is being malicious, and assuming it is beyond the frame of the circumstances to properly be able to correct them.

(Some of this can still be done to be charitable, but I always say it's no good to squeeze out all your water for someone who is dried out and you become dried out instead. You dole out what you can afford to, and put limits at some point before it's too much. And frankly just looking out for yourself is valid plenty of the time, so long as you yourself are not actively malicious or be that way when it's not forced.)
