Answer:
This depends on the situation and the rule that I have to violate. Let's say for example, there was a guy trying to kill/kidnap me. Basically, a life-or-death situation. I would not attack until he took the first action, such as throwing a weapon at me or hurting me first. Then, I would legally have permission to defend myself since he attacked me first. This wouldn't affect only me, but also my daily life. Firstly, it wouldn't look that good on a job application or a resume (for college), which depends on your age. This is only an example and as the situation or the rule to be violated is not specified, my decision may change.
Hope this helped!
