Making Ethical Decisions

A snippet from Religious Dispatches caught my eye:
K'vod Habriot is Hebrew for "human dignity." It is a Talmudic principle that is applied in the Jewish legal context, and in service of social justice. Fundamentally, it is the idea that respect for an other's individual dignity as a created being must figure into any ethical decision.

What factors do you use to make ethical decisions? What does it mean to factor in another's individual dignity as a created being in making decisions? How would such an approach change the way you make decisions on a daily basis?
