Does making money bust your conscience?

I was talking to a friend who recently got involved in "another" MLM kind of opportunity. Well I am not sure if it is MLM but the ignorant me tends to conveniently lump anything and everything concerning selling products by word of mouth or through an online network of leaders, distributors or what-have-you under the MLM category (or network marketing, whatever). Not sure if I am right but I don't really care lol. :P Anyway because he is a good friend of mine, I was racking my brains to think of ways I can help while he was telling me about his new passion. I was in fact looking at the product list and scrutinizing the text to see how any of the products might be of use to my family or me. I then asked him whether the products have been patented and if he can provide more details on how WOW the products claim to be, etc. But guess what? He replied that the products are not patented then went on at great length about how I can RECRUIT people, form teams and make this a stream of income. Everything will be done for me since the awesome system is automated online. Apparently he wasn't the least bit interested about the products (though he did try them out for the sake of "professionalism") and if I may say this irresponsibly, he couldn't care less if what he is selling is dirt or curd. And when I commented that this sounded like a pyramid scheme, he beat his chest and said that the company HAS PRODUCTS. In his mind, having products automatically separates the company from pyramid schemes. In our quest for money, do we sometimes need to take a step back and ensure we are acting responsibly and in good conscience? Well... to each his own.

If yes, drop me a note and I shall remove it immediately and offer my apologies. Thanks in advance! :D
