Act 2 #2

2.It is sometimes necessary to take decisive, preemptive action against someone because of what you fear he or she might do later.

This statement is very similar to Act 1#1, "It is sometimes necessary to do things you know are wrong in order to achieve an important goal." Both involve the justification of something wrong. However, I agree with both. Rash decision making is something everyone tends to do. Imagine you are at a bus stop, waiting in the rain. You see a big, shady-looking man with his hood over his head, shielding his facial expression from you. He's fidgeting with something in his pocket, and while concealing whatever he has, he begins approaching you. I bet fear is going through your heads right now, and you start making choices, like running away, calling someone for help, or preparing to fight back. However, interrupting your train of thought is said man, muttering something incomprehensible. Right when he is about a foot away from you, he turns to you, and, acting on instinct, you punch him in the face and run away. 

You took a preemptive action for fear of your own well being, harming his in the process. You later find out that he was a lost tourist, and was prying open a map from his pocket so you could help him find the nearest Pizza Hut. You feel guilty, and regretful that you didn't help the lad, but was it really your fault? All he got was a punch to the face, but what if he was hostile? You could have been assaulted, mugged, or maybe even killed. I think, once our options are weighed, it is OK to make a decision defending something, as long as it is reasonable. Is murdering someone who walks toward you reasonable? Absolutely not. Unless you know for sure what the outcome of his/her action is, try and make sure you know the outcome of yours.
