My most ethical business idea was in first grade where I made jewelry from trash and sold them to my friends. So I don't think I should be the one to write a guideline of what's considered morally correct and what's not.
It's also not very delightful to tell people to do exactly the opposite of what you already did, only because you can't live with your own guilt.
We all do things that we are not proud of. Probably should save the whole being a champion of justice for yourself and leave me out of it. Because I sure will do plenty more of naughty behavior in the future. And being seen as a better person than I actually am only makes it harder for me to write apology songs later.
