first of all, Christianity does not frown upon strength. instead, it applauds strength. those who have the mental or physical strength to achieve great things are encouraged to do so. we want to make life better. i'll agree that there is hardly (if at all) any such thing as a selfless act. but sacrifice for a cause does exist. i do think that we human beings can be strong, can help out for our own purposes or just on a whim. Christianity is not trying to impede that. i also disagree that such people are "stagnant." those who seek change and become that conduit of improvement are anything but stagnant.
like you, i value strength. strength to achieve feats of physical power, as well as mental strength. strength to continue with a charge, even at the end of that capacity. as you said, individual lives are important, but if the situation occurs, it is noble to give that life for the cause.
like you, i value honor. honor and integrity. these are core values to christianity and i do not see how you overlook that. honor is very important. revenge, however, as i infer you may include in that definition, (such as the case "to avenge my dead brother's honor in battle! etc.) is not honor. revenge is a product of hate. i beleive that an honorable warrior would always combat defensively. in defense of ideas, property, or fellow people such as friends, family. i think it is dishonorable to "strike back".
as i've stated before, achieving great things is something we all aspire to do. Christianity does not shun this either. it's not communism. you seem to have equated it as such with your views of it. and as for nature, nowhere in Christianity does it say "ignore nature". if anything, it holds nature (as God's creation) in high regard, and that we should respect the other life of this planet. why else would God instruct Noah to take with him 2 of every animal?
the whole point of this post is, i am doing what i see as the honorable warrior, defending my beliefs and the faith's ideals from what i see as misinterpretation or inaccurate understandings.
