I must respectively disagree, peace and aggression are two opposites on a spectrum. If you know something I don't please provide some instruction, because the underlying premise is Love for all and sure you could twist the definition of aggression and say you aggressively love all, but you could also just say that you love to love. It is all about what is in your heart, even if you are doing right yet hold aggression in your heart then that betrays you and you aren't being true to yourself and all things are known by truth, and there is an internal reaction to aggression your heart can't be at two points at one time. It seems there has to be a better term or way to define the "aggression" in the case of resisting evil, because he who did it only acted aggressively once as far as I know and even then it was said that he had done so out of zeal, not aggression. From my understanding defining behavior is tough as there are so many different words that mean similar things, but I think of an aggressive animal when I hear aggression and how these animals behave towards other animals and humans then I think of humans who may not act as violent, but their is something different about the aggressive person just like in an aggressive domestic animal whether they just hate other people or don't care about them and don't want to be bothered by them.
