Except, perhaps, consideration for how their extreme actions may negatively impact the lives and standing - such as it is - of the MAP community in general. Granted, it's really hard to focus on the big picture when suffering from the emotional tumult of your life being destroyed, but I still think it's a legitimate thing to consider, i.e., how willing someone may be to risk taking innocents down with them when they know their own downfall is imminent.
