I agree. The only problem is when you insist on extremes. Justice is about a constant struggle. There is no absolute good in the real world, so we have to wrangle over it. I like that, personally.
On the other hand, pacifism has a tradition of being used for drama and political change. Martin Luther King used it to stand out from the angry oppressed and prove the righteousness of their claims. I hear Gandhi made waves. And the Squadron Supreme guy Dr. Spectrum turned to pacifism for awhile when he accidentally killed a younger superhero in the original version.
