I think it's like doing any other thing that you shouldn't be doing. Eating this donut will make you fat. Buying that car will increase carbon dioxide emissions

I think it's like doing any other thing that you shouldn't be doing. Eating this donut will make you fat. Buying that car will increase carbon dioxide emissions. Not helping that random stranger is egoistic. We make these decisions all the time, every day. I at least try to be honest about what I'm doing. :-)
