Oh boy, that’s a loaded inquiry!
My ethics are centered around personal choice, and how it effects your environment and other people. I don’t think of any certain act as inherently “wrong,” because the situation always changes.
A few examples:
-If you are consciously making a choice that you know would hurt someone/thing else, it’s wrong. That is, if you can help it without undue stress on yourself.
-Avoiding new information that impacts your live-style (because you don’t want to change) is wrong. It’s not that hard to change—one small day at a time.
-“Going with the flow” because you never want to think is wrong. It’s your responsibility to know the consequences of your habits when and if you can.
How did I arrive at this?
I’ve always been OCD about ethics, to the point where I had no self-assurance of my own thoughts or abilities. I‘d come completely undone if I someone discounted my careful thoughts, or hard work. After opening up about it to various friends, I figured out that most people weren’t as conscious as me, and weren’t carefully listening when I thought they were. And as pompous as it sounds (and felt to me,) realizing that allowed me to separate my self-identity vs. others perceptions of me.
After that, I stopped seeking validation for my thoughts and trusted myself, so I’m better at processing incoming information and acting morally on it. (I still ask for second opinions, but now I’m better at assessing what other’s say).
Letting other people arrive at the answers for you is laziness. Just people someone else assures you something is right, you have a responsibility to listen to that nagging voice in the back of your head and investigate the situation properly.
With that, you are also a person that deserves ethical consideration. If you can’t afford yourself that, you won’t be able to act ethically in any given situation.
