Well, when I look at a situation, I just tend to ask, "Would I want someone to do that to me or my possessions?" Keeps me away from the basic things. You know, killing, stealing, vandalism. Of course very few of my morals are set in stone. I'll kill if it's in the defense of someone or something I hold dear. I'll steal from someone if it's something they received through elicit actions. I'll vandalize property if it's necessary to make a point. Every rule has an exception, and that's why I allow my moral code to adjust to any situation presented to me. Of course these are extreme examples, which are unlikely to come about, but they're still potentials worth considering. Also, consent is a big thing for me. I think most things are acceptable if the individual at hand consents (while free of coercive or chemical influence) to them. But, again, morality as a whole is one massive grey area. In extreme situations, some things have to be compromised for the sake of the greater good. Or something like that. I'll admit I probably got off track somewhere in this post. On a side note, I also carry a deep reverence for death and the dead which influences a portion of my moral code. I'd say that portion is probably the part that's most unchanging.
