Affiliate Marketing Secrets

I am an affiliate marketer, and I have the products of the advertisers I sell. An idea would be selling online or even making videos with my show I have and making commercial like ads in between topics in videos. I know these are trying times and money is tight for many, but as a seller, should I feel bad? Should I feel bad for selling products as an affiliate, independent contractor or salesman? Asking for rational comments, not just a simple answer, greatly appreciated!
