Universal Principles?

Are there universal principles, or would it be better to say humanistic principles, that all "normal" humans agree upon? Such as murder? Do all humans agree on this issue? If not, do they disagree because they are "abnormal" or do they disagree because they do not hold to same principles, therefore suggesting there are no such sorts of universals.

Everything hinges on where one falls with respect to this question. Now there is unlimited possibility connected to both, nevertheless, one must it would appear take a position with respect to this question. Even doing nothing, is ultimately, doing something. The question is simply why we do what we do when we do all the crazy things that we do. And that's a lot of do-doin'.

Ethics and Faith

Should how we act be influenced in any way by faith? If so, how so? Who's faith exactly? Will any faith work, or is there a "right way to walk?" Are we to take serious a claim to action that grounds itself in someone's belief? For example, that homosexuality is "wrong." Or that abortion is murder?

Should not our ethics, or common morality if you will, be supported by more than mere faith? If we assent, however, upon what do we then ground our ethics? Must not any ground involve some degree of faith? At what point does fact fade to faith, and how can we know when we have crossed the line?
